im going from efi to carb and this is what i was planning on doing to the car.
i have it 306 with stock style pistons
plan on getting 351w heads and porting them out
getting victor jr intake
650 holley carb. is this a good setup? and how much horse on the engine do you think it will have?
also have .512 lift cam

351w heads (C9 or D0 castings) with some mild porting work quite well for a ford casting head, but a victor jr intake is gonna be big for anything on the street. if you plan on driving this things around town i'll recommend a performer rpm airgap instead. also if your going to go 650 grab something vac. secondaries cause a 650 DP is just too damn much for a 302.

i have experience in this area as my 12:1 306 with C9 351w heads and a 300 duration .500 lift cam has had a 600 vac. secondaries carb, then a 650 DP, then a 650 vac. secondaries. (barry grant is the way to go)

honestly, with your lower compression i'd put a BG road demon 625cfm carb on the performer rpm or rpm airgap and i think you'll be really happy

how much horsepower will that give me?

HACKGT350

after its all together take it to the dyno and find out we cant really give out answers to stuff we dont know

dthompson67

will do that after i get it together.

HACKGT350

you should feel a big difference and putting down some good numbers though

dthompson67

what you mean? from switching form efi to carb?

deanzawistowski

switching from efi to carb wont give you more horsepower, youll get more power out of those heads and intake and your cam

dthompson67

thats what i meant.. i mean would i feel difference from what i am used to know then the set up i mentioned.
