I have a 68 Charger on its way and wondered if it is built accordingly, how much hp at the crank should the motor put out?  Thanks in advance for any input...can't wait to drive it.  Justen (newbie)

Congrats and welcome to the site. Which engine?

Sarcasm detector, that's a real good invention.

I guess some info would help:

The engine is a 440, 30 over Big Block Dodge. Forged TRW 10.75:1 pistons, factory crankshaft & rods, Stage V Chrysler cylinder heads, Engle Hyd camshaft (.517 lift, 282 duration, 108 lobe center), Edelbrock Torker intake with a Holley 830cfm carb. MSD 6 al ignition box, MSD billet distributor and spark plug wires. The exhaust system consists of a 1 & 7/8 Hooker Super Comp headers, 3" tubing and 40 series Flowmaster mufflers that were all coated by Jet Hot. The transmission is a rebuilt A8333, 4 speed manual with a Lakewood bell housing and a Hayes 11" clutch assembly. 4.56 gears out back.

Thanks

Well a part of it depends on who built the motor & did the machine work.

Them some deep gears & with a 4 speed, ya better get a membership at the local tire store.

Only one way to find out, which is to put the thing on rollers and see what numbers you get.  Or better yet, forget the HP numbers-take it to the track and see how the two of you perform and look at those numbers...

You'd be surprized these days. Jderek, Wouldn't be too worried bout the HP as much as how much you can put to the ground. I got a stock 440 with 4-speed I can't hook in a fifty acre field.

I have seen that 68 on Ebay for a VERY long time...it looks nice.

Also not sure what you spent but it was way out of my reach.

Kinda of a restored Charger that is tubbed out, different combination thats for sure.

Congrats!!!

Goodness, $54 large??? :o

I like the fact they painted it a factory color & not some belly button color.  Could very well be the original color of the car?
Engine bay needs toughened up.  Beautiful ride though.  I've lusted over it every time it's been listed.  It looks like it was built right?






I don't know about traction issues?  ;)   That's a bad ass look.   :2thumbs:

Holy shit! :o :o :o That car is a dragster :drool5: :drool5: :drool5: Would be fun to drive! :cheers:

What would you suggest to toughen up the engine?  What kind of 1/4 mile times with that 4 speed do you guys think? Thanks

That is one tough looking car!  1/4 mile times are still tough to predict.

skip68

That car needs more motor.   I'd guess high 12's low 13's.

Hopefully I can drive around town and drive it to the track here...probably turn too high rpm for the highway....will know in a few days.  What would be the first motor upgrade you suggest?

Yeah, 4:56 is a lot of gear but the tires are pretty tall looking too so...

How tall are those tires?

If they are 31 inches it wouldn't be too bad on the highway.

Before you going changing things, drive it a summer and see what want to correct. Then you have all winter to fix the stuff your not happy with.

With the hydraulic cam and 456's you are going to run out of motor before the quarter mile mark.   Fun on the street but you'll want to go with Eddy heads and a solid cam.

With tires that tall the 4.56's shouldn't be that big a deal at highway speeds. Only one way to find out.... :D

http://ramchargercentral.com/index.php?action=calculators

A little calculator to play with. Say the stock diameter was 27 inches and you now have 33 along with the 4.56 gears, it acts like a 3.73 final drive.

Like I said, before changing stuff get to know the car first.

Nice car ! I'm assuming that the engine builder had the rotating assembly balanced during the rebuild ? If that's the case then you'll be fine spinning it up to 6000 but i wouldn't push it any higher. You can install a 6k chip in the MSD box and i would do that anyway to protect the engine in case you miss a shift.  :yesnod:

The cam isn't radical at all...it should idle with a nice lope and be very streetable. With Hyd lifters you're limited to 6k rpm so there's no point revving past that point....it won't make anymore power. Depending on cylinder head flow it should be in the 450hp/500tq range with the sum of it's parts. As for 1/4 mile ET's it depends on how much the car weighs and how well you can shift. Traction won't be an issue with the big tires and 4 link.  :icon_smile_cool:

The 4.56's are fine with a 33in tall tire. Basicly the same thing as 3.55's with a factory height tire so you won't be spinning the snot out of it.  ;)

As for the build quality it sure looks extremely well done. I'd say you did very well on this deal  :2thumbs:

I appreciate your input.  I will get it this week and have a better idea how it drives.  The video I received had a nice lope.  An auto would probably be better for drags but have always liked shifting.  Will update when it arrives and probably have more questions I'm sure.  Thanks again.
