Got a 69 truck 383 thats going to be going into my Satellite and was wondering what combonations you guys run on you street motors. I do plan on racing it occasionally but it looks like its gonna be getting a 4spd so I'm not real worried about track times. It does need to run on pumpgas and I might use my old Isky 505 cam I've got laying around...

It'll run on pump gas fine , compression is only 9.0 unless it's got domed pistons and or tiny combustion chamber heads .

The cam is probably too big , get the big summit cam , 1 3/4 tube headers , if possible get some closed chamber heads , 516's with 1.74 exh valves and a good valve job , bowl work ...

I used a Hughes 223/230 dur .504/.514 lift in my '70 RR 4 sp and it was a great street motor. I wanted to keep it a stock appearing car so I don't think going much bigger on the cam would have been useful. I was running 3.23's and it could have used at least 3.55's to really scoot. I think I pulled 14" vacuum and it had a moderate lope. Never races it.

DP4B intake 4 hole 1/2 inch spacer, Holley 700DP, headers (1.75 is fine) and 3.55 or 3.91's should be a nice set-up

What he said...make sure it has good compression or it won't matter what you try cause it'll be a turd.

what's your budget and how much work do you wanna do?

I took a low compression 2bbl 383 from a C-body, dropped a 440 source kit in it, making it a ".010 under 440 in a low deck block"

10.5 compression, RPM intake, OOTB eddy heads, 750HP carb, and a XE275HL hydro cam, for a fairly easy and mild 500 hp, 535 lbs torque.

total cost was probably 5-6K?

or you could go budget build, get new pistons or zero deck the block, get compression up to 10.0:1 or so with stock iron heads, cam, etc. and still make an easy 400-450HP with the stock stroke 383

Well the 400 is like a bored 383 and my son runs a stock stroke 400. Here is his combo:

Stock balanced shortblock with 383 steel crank and it has KB pistons.
Eddy RPM heads milled to get 10.6 comp with the KB pistons.
MP .557 cam and Isky ductile iron rockers.
Eddy RPM intake with 750 DP.
Stock Mopar dist we curved with MSD 6A box and we run total timing at 36 with no ping running on 93 pump.
CPPA 2" headers with 3" exh system.

It is in my sons 72 Dart that weighs 3550 with him in the car. With 3.91's he has run 11.40's @ 117 and its a street car he drives to the track. Ron

Thanks for the input guys. I dont think it'll be too hard to get the power I want out of it. I think the car will be fairly light when I get done so hopefully it wont take too much to motivate it.

Compression,head flow,AND THE RIGHT SIZE CAM will make any motor a good running one.Just don't over cam it unless you want to run deep gears and a high stall speed.
