351w build?

[Venomous94Cobra]

hey guys i think im having some issures with my 302 and im getting ready to take to car apart anyways to redo alot of stuff so i figured it would be a good time to stuff my 351w int here, tell me what yall think this motor would put out with this setup and this is with parts i already have including a 94 roller 351w motor.

94 351w efi roller motor (non stroked or bored just factory 351w)
AFR 205's with 58cc chambers
comp 270 hi energy cam
comp 977 valve springs and retainers
comp hi energy 1.6 roller rockers
red top injectors (30cc i think?)
90mm accufab throttle body
90mm lighting maf

I know ill need a oil pan swap kit, but i want to run long tube header, ive looked around but cant really found any good quality swap long tube headers for a 94-95 chassis? also what intake would be best, im aiming for higher rpm power so i was think about either a trickflow box r intake or edelbrock lower intake with a wilson elbow?

Edelbrock spider efi lower would be great ... Most guys that do this swap I've seen use the fox 351w swap headers

awesome thanks man

you can use fox body long tubes. thats what i used on mine, but i had to mod my mid pipe.

here is mine

anyone have any idea how much power a stock block 351w will make with my setup?

 

[rz5.0]

More than a 302.. wild guess 375

Mine made 345 with AFR 185 heads (72cc Combustion chambers) Trick Flow R Intake and a custom cam. My Compression Ratio was really low. But that set up with the right intake should push you over the 360 mark pretty easy. I fully expect to be close to 400 with my new set up soon to be fully installed. I went with Custom Long Tubes from Accufab, I had 351 swap headers before that, the shorty version.

wow thats not much more than i got now, when they dyno'd it in utah it made 330whp

I was at 8:4 compression b/c it had a set of heads on it that were designed for boost and I was running NA, Plus I had a not properly sealing lower intake that was leaking. Still managed to run a 12.5 regardless.
