critique my 347 plan

Just ordered my 347 stroker from Woody @ Ford Strokers.



This is the plan - hope someone will chime in and not turn this into a 331 vs 347 debate.. For my 1995 Rio Red Cobra - keep in mind this is a street car, looking for usable TQ/HP from 1500 - 6500 RPM.

347 stroker built by Ford Strokers, 10.5:1 compression, flat top pistons

AFR 185 heads, 58cc chambers, 2.02 intake valve, 1.60 exhaust valve, will upgrade to the larger springs I would opt for the 'Competition 185's, from what the guys at AFR told me the exhaust is raised and it has the dual spread pattern for the headers, so you dont get the crimp where the header bolts are.

Edlebrock Performer II intake I would suggest either a Trickflow R or Vic 5.0, or at least a Holly. Again, your cam builder will know better than me, but the rpm range on the Performer II is 1500-6500, BUT thats on a 302, so a 347 will be more like 1300-5700rpm, if the displacement % difference stays constant in the rpm range.

1-5/8” long tube headers I would also suggest 1 3/4 LT's, 3" collector and a decent catback. Dont wanna choke the exhaust

Either 1.6 – 1.7 rockers, depending if I can use my stockers I would suggest a stud mount rocker, and just get whatever ratio your cam builder suggests

30# injectors I would suggest 36's or 42's, since its always better to have too big of an injector than too small.

90mm mass air meter Good, LMAF is a good cheap choice

75mm throttle body Good enough, 90mm may free up a couple hp, but maybe not

Walboro fuel pump A 255lph would prob be plenty.

Ed Curtis cam - still waiting on the recommended specs
