Just getting into my first Mopar build👍 unfortunately I cannot pour all the money I want into my car, but I have a few things to start with. I have a 1977 440 and a 1970 383. Both the bottom ends in the motors are great so I can stick with stock Pistons and whatnot.
My question is what's going to be the better build for a consistent strip car? I'm putting my setup in a 1973 Plymouth scamp with 4:30 gears
Parts I have:
509 lift 289 duration cam w/lifters and matching springs
Factory 906 heads w/ 1.5 ratio roller rockers
Edelbrock street master intake w/ Holley 750 double pumper
And an msd digital 6 ignition... The rest of the Money I have will be spent on a starter battery...etc so what motor should I put together with that setup? I know the 440 had horrible compression but will it still perform better than the 383?
 
A friend of mine's kid put a 8:1 compression 440 (stock 4 bbl) into a 74 Dart with a fiberglass front end and it turned 12:45 on pump gas....


Go with the cubic inches....
 
The 383 will make more power. That cam is not worth a crap on a low comp motor.
 
well I don't know about that cam not working for you. I have that same cam in my 76 440 engine with 452 heads, 650 Eddy carb, Edelbrock intake running 3 :23 gears and I can turn the car around in the middle of the street on take off If I am not careful so for what it is worth. But if I had it to do over again, I may have went with a 383. my opinion, not much difference to me.
 
I would use the 383 for now, and build the 440 for later . stock/stroked
