Need some advice on my engineplans.

[Reidar]

Hi guys!

I have a -75 Charger with a 360 engine im planning on using as a 1/8 mile drag car.
Here where i come from we race in 3 classes: Bracket (set your own time), Street (8.7 sec) and Badboys (7.7 sec)
Im aiming to build a car that can be competitive in the street-class.

The engine is going to a local shop to be checked and bored 030" over.
I plan to buy this strokerkit: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8053931238
And Edelbrock performer rpm heads: http://store.summitracing.com/partdetail.asp?part=EDL%2D60779&FROM=MG
Weiand X-CELerator Intake: http://store.summitracing.com/partdetail.asp?part=WND%2D7545&FROM=MG
Comp Cam: http://store.summitracing.com/partdetail.asp?part=CCA%2D20%2D228%2D4&FROM=MG
And i have a Holley 750 Double pumper carb.
Im getting my 727 overhauled and rebuild with a reversed pattern, manual valvehouse.
Have a 8 3/4 rear with the 489 house. Installing a spool and 4.11 gears.
Offcourse i also plan to buy a lot of other things, but i guess this is the main parts.

What do you guys think? Is there anything i havent tought of?
Any help and advice will be greatly appreciated!

Looks good to me Reider !  The only thing i might change is the intake manifold. The Performer RPM Airgap is an excellent piece and being a dual plane design....will make better torque down low than the single plane will. My buddy has the Aigap on his 408 stroker with E-heads and the car pulls very strong down low. With a heavier car, torque is what you want & need to get it off the line. 

The Eagle parts are very good and the cam is well matched to the rest of the combo. A 3500 stall would be my choice with the parts outlined for this car. The 750dp is perfect.

[Reidar]

Thanks for your input, Ron!

Is this the intake you would recomend? http://store.summitracing.com/partdetail.asp?part=EDL%2D7576&autoview=sku

I have been looking at this torque converter: http://store.summitracing.com/partdetail.asp?part=HUP%2D24%2D35&FROM=MG
3500 stallspeed from Hughes.

Have your friend ever tried his car at the track?
Do you think my 75 charger can make 8.7 sec on the 1/8 mile with this setup?
I know its a heavy car, but nobody else drive cars like it. I find that pretty cool!

Thanks again for your help! 

[firefighter3931]

Reider,

Yep, that is the manifold. 

For the converter, i would look at a PTC 9.5in unit. They go for ~ $450.00 or so and are excellent quality ! The part # is: PTCTF95 Make sure to order the matching flexplate and hardware at the same time. 

http://www.coperacingtrans.com/torqueconverters.htm


My buddy's car is a streetcar so no track times as of yet. I will say that the stroker is comparable to a very strong 440 with lots of low end power which is not typical of most standard stroke smallblocks. He is also running a smaller cam (Comp 275HL) and 3.55 gears with a 2600 stall.

I don't know what your car weighs but with the build outlined above an 8.7 1/8th mile ET should be a cakewalk as long as it hooks and everything is working properly.  Another friend has a full bodied Cuda with an iron headed 440 that makes similar power to what this 408 will make and his car runs consistent 7.60's with slicks and 4.10's.




Ron

[Reidar]

Thanks again Ron, for helping a newbie!

I was looking at the PTC unit. Not much info on the site, but if you recomend it, its good enough for me!
So what i need from them is the PTCTF95 converter, but the 10236 is for external balance. Im thinking with the strokercrank i need an internal balance?
And as my car is at a garage a while from me, im not sure if its P4120464 7/16 & 8 or P4120465 7/16 & 6 i need. Maybe you know?


Reidar

[firefighter3931]

The stroker rotating assembly will be internally balanced. The crank will have a 6 bolt flange so the correct flexplate is the # 10230. The PTC converters come with a 7/16 lug for heavy duty applications....but check to make sure when you order the converter, just to make sure.

John @ CRT is a top notch guy to deal with and he won't steer you wrong. I've bought several items from him and will continue to do so in the future. 



Ron


Ps. If you're looking for a nice SFI harmonic balancer...check out this link. Really nice quality, stock pullies line up and good to 12,000 rpm....indexed for easy timing adjustments !     The price is right too. It's designed for a 71 and up smallblock with the passenger side pointer on the timing cover (see note in description).

I'm not sure what happened to make you feel like that, but he's done right by me and thought I would pass his name along.

FBO a nice guy ....maybe if you agree with him but if there's an issue with his stuff or his opinion... look out.

Ron

He (Don) is entitled to voice his opinion(s) of people, just as others on this board do on a daily basis. It still doesn't change the fact that he knows more about performance Mopar engines than most.
Ironically, most of the posters stories I read in your links, seem to be very positive in their dealings with Don. Things just happen sometime when you're in business and you end up making a few enemies along the way. I'm done.

Hey Whitehat, i don't want to get into a pissing match here and you are certainly entitled to your opinions. The guy is arrogant and a know it all. Question him on something and he insults you and runs away. Some GURU    I haven't seen any advice on here that couldn't have otherwise been answered by another member. Trust me, the sun doesn't rise and set at FBO 

It's his attitude that is irritating and the lack of tact when dealing with customer issues. His "trust me" attitude (see racer brown cams in thread above) in terms of tech questions means he doesn't care or can't provide the answers or doesn't want to provide the answers.  If he wants to submit an opinion on a specific topic then he should be able to support it w/o namecalling and childish accusations. Trust me, this is not isolated behavior....he's been banned from other sites for similar behavior. 

Don needs to spend some time at finishing school. 



Ron

[Reidar]

Thanks for all your input guys, but leave the guns at the door when you come in..

I have another question, if you would be so kind to help me a little more.
Im having a hard time figuring out what i need from MSD.
I want a complete msd ignition-system, but I cant find a set for my engine anywhere?
A lot of people recomend the MSD 6AL system, but what do i really need?
Im guessing controlbox, distributor and coil?

Anyone have any experience with this?

Reidar

[firefighter3931]

Thanks for all your input guys, but leave the guns at the door when you come in..


Reidar

No guns here Reider....we are all gentlemen and behave accordingly. 


The 6al is a good box and comes with a rev limiter which is an added bonus. MSD does make a good line of distributors which are easy to dial in....but i've also had good luck with the MP distributors as well. The MSD blaster coils are excellent.  I also like the MSD superconductor 8.5mm plugwires. 


Summit should have all these parts available on their website.



Ron

[Reidar]

With the pistons and heads im going to use im gonna get about 13.2:1 comp.
Have heard about problems with the output from the msd box with high comp.
What do you think, Ron? 6AL handles that comp?

Reidar

Reider, lots of guys run the MSD 6al in high compression applications. It's just a matter of closing down the sparkplug gap to ~.035 - .040 from the normal .055 -.060 to keep the fire lit. 


That's a LOT of compression....do you really want that much ?



Ron

[Reidar]

I just want the most bang for the buck!

Quote from the strokerkit vendor:
"# ROSS part # 99787  -21cc DISH FORGED  PISTONS .030,  pistons 10:1 comp w/62cc head, or 9.4:1 with a 68 cc head (((OR))) ......
# ROSS part # 99789  4cc DOME TOP FORGED PISTONS .030,  pistons 13.2:1 comp w/62cc head, or 12.2:1 with a 68 cc head "

Im using the edelbrock heads with 63cc.

I going to use this car 95% strip only, so i dont worry that much about streetability.

[Reidar]

Hi again!

Was looking around on summitracing.com and found the following:

Blaster coil http://store.summitracing.com/partdetail.asp?autofilter=1&part=MSD%2D8228&N=700+4294908110+115&autoview=sku
(Only blaster coil i could find, but doesnt look like it fits earlyer engines than 1990?)

Box http://store.summitracing.com/partdetail.asp?autofilter=1&part=MSD%2D6420&N=700+115&autoview=sku

Distributor http://store.summitracing.com/partdetail.asp?autofilter=1&part=MSD%2D8534&N=700+4294908110+4294840106+115&autoview=sku

Maybe a stupid question, but when they say it fits 360 engines, it doesnt matter that mine is a 408 rigth? It just a question about the fit?

Reidar

[firefighter3931]

Reidar

Those parts will fit fine....there are other coils available the look more stock....shaped like the factory style. The 408 is basicly the same engine as the 360 so that distributor will be OK. 


Ron

[mikepmcs]

You won't really be able to fit that coil in the stock location without some modification.  I don't know what you are going for as far as stockish looks, but obviously Ron is right with a more stock looking coil like the MSD Blaster 2 if you desire to go that route and you can mount your ignition inside the car or somewhere else if you desire. 

I myself have an MSD 7-AL2 ignition with an 8251 coil(recommendations from this site) but had to mount them to my passenger fender.

Hello again!

As you all probaly know planning a project isnt allways as straight forward as it seems..

Im thinking about doing a little change. 415 instead of 408! 

Bore .060 over and use concrete in the block.
Same strokerkit, if they can deliver pistons 060 over.
Changing the heads to Indy instead of edelbrock. (Have found a guy that can port and machine them)
Indy intake also.

And I think im going with the solid roller cam! ITs on this point I need more of you guys input!
What cam will you recomend? The Indy heads allows up to .650 lift.

Im also, like you said Ron, going down on the compression. Trying to come in around 11:1.

What do you think?

Well, it sounds like you're stepping it up....no problem with that ! 

As for the overbore ; have the block sonic checked before you order any parts. That will tell you how much you can safely overbore without compromising cylinder wall thickness. The hardblock is fine for a race type build but it will create heat issues if you plan to street drive the car.

11:1 compression is fine as long as the cam profile is properly matched to the rest of the build. Solid rollers make killer power but there is also added maintenance when running these types of cams. I would look at an "endurance" profile which is easier on Valvetrain parts and requires less frequent valvespring replacement and roller lifter rebuilds. The really agressive "race" grinds are very hard on parts. 


INdy heads are very good and as longs as you have someone willing to work on them for you....i see no problems going in that direction. Depending on the cam profile and how well the heads flow ; you will be at 500+ hp and have TQ out the wazoo ! 


Comp has a number of solid roller cam profiles in the master lobe library that could be used in this type of build. It will most likely be a custom cam designed specificly for the build and car.

Sounds like you're going all out Reidar!    We've got a quarter mile strip about 20 minutes from here and it looks like a lot of fun!
I look forward to hearing about your results.

OttawaCharger;

Ron & myself go there quite often, as well as the cruise nights, haven';t seen your Charger before, have you just picked it up recently?

You are correct.  I just picked it up last spring and its in the process of being restored.  So far I've only completed the tear-down so at this rate it could take a while! 
Next time you're going, let me know.  I'd love to see it!
