A few suggestions.

Have the block checked for cracks

Recondition the rods and have them shot peened

ARP rod, main and head bolts

Stainless steel valves

[mally69]

Loose the eddelbrock carb  ,, get a holley or demon  much better

for $200 more you can get a good forged piston
Most Hedman headers will NOT clear the mini starters
I would use a Holley or Proform carb

[dukeboy_318]

not planning on using a mini starter, just the stocker, will that be a problem???

[terrible one]

Really? Why is that? Is that a usual case with headers on these cars? I figured a smaller starter would mean more clearance?

[Chryco Psycho]

Hedman has a different design for their headers putting one of the tubes right where the mini sits 

[Steve P.]

I have Headmens and had to do some heating and bending to make the mini started fit. It seams that I have allllllways had to do some extra fitment, but this time was BIG....... 

[dukeboy_318]

any other reccomendations for headers that run less than 200

[Mean 318]

Holley performer! Eddelbrock SUCK! IMHO... I wouldnt put that "stuff" on my lawn mower!

[dukeboy_318]

forgot to mention that i am switching back to holley after readign some of the issues with edelbrock carbs

[chargerbr549]

I have a set of the Hedman 78070 shorty hedders on my 74 Dodge 440 pick-up and I am pretty sure that you can't use the stock starter but I maybe wrong, I have no clearance issues with them around the mini-starter the only area I remember that was close was one of the collectors comes close to the pan rail but that worked out fine, I have run these hedders for about 6 years now and they have worked really well for me.

Heres my combo that has my 73 SE in mid 13s 400 stock pistons ,windage tray from mopar performance#4120998 (can be installed without pulling engine) .038 head gasket from MP#4529455 Summit cam #K6901 comes with lifters Flowtec headers452 heads ported 8008 Wieland manifold and a Holly duel feed 750 .Transmission and converter are stock. Rear is 273 car is a dog offthe line but when Ihit 2nd you can fell it pulling

not bad, upgrade the trans and different gears you might hit high 12s.

[dukeboy_318]

another question, what would you guys reccomend as far as pushrods, mine arent bad, but im going for durablity so im replacing them and the rocker arms, also what valve springs??

[dukeboy_318]

 

[firefighter3931]

The list looks good....few things i would change though ;

(1) Performer RPM intake manifold instead of the Wiend
(2) PTC 11in torque converter instead of the TCI

I would use the MP heavy duty stamped rocker arms and a set of chrome moly pushrods. Comp Cams # 911 valve springs will work fine with that VooDoo bumpstick....or go with the recommended lunati springs....your choice.

Not sure on the oilpan....but with an HV pump you will want something better than stock. A windage tray of course to keep the oil in the pan...where it belongs. The 6qt Hemi pan is very good but i'm not sure if it fits in a 74 Charger. 

Headers sould be a 1 3/4in primary long tube design....no shorties. Again...not sure what fits well in the later chassis.

Yeah im planning on an aftermarket oil pan, ive heard some bad things bout the edelbrock performer RPM intake.  Im also thinking of going a little bigger on the cam, maybe this one , similar to what hot rodder is running,

im also getting a milodin windage tray and going to get some new valves too.

[dukeboy_318]

will i have to have my heads macined to fit these springs on it???

Nothing wrong with the RPM intake manifold. 

The 268* Voo Doo cam is the right choice for a 400ci engine.....the larger stick for hotrodder's motor would be too big....remember he is building a 500in stroker. Don't overcam or you will be sorry.

http://store.summitracing.com/partdetail.asp?part=LUN-73815

Nope....those springs will work fine. Basicly a stock spec (dimension) high performance spring. 



Ron

[dukeboy_318]

okay will keep orginal cam,

[dukeboy_318]

my other ption is  a 472 stroker kit from 440source, dont know yet, again looking for durability but power at the same time, i am saving up for the 440source heads though

[Hot_Rodder]

Looks to me like you decided on the 472 cid motor, lol. Either way, enjoy.

[dukeboy_318]

yep thanks to some 3 hrs of research and half hour on the phone with 440source. oh and you guys

[375instroke]

I'd use HP manifolds before I use shorty headers.  The shorties don't flow any better.  The length of a headers contributes greatly to their efficiency, not just their tube diameter.  You're exhaust valve and port are the real bottlenecks.

[dukeboy_318]

im going to end up stroking this motor and running flowtech headers, seem to be a decent choice based on flow and price
