Generation IV Internal Engine - 402/408 w/ AFR 205's?
08-07-2008, 10:28 PM
I am in the early stages of planning a 408 or 402 build. My question is has anyone ran AFR 205's on a motor like this with good power success? I know the heads might be on the small side for this size stroker just wondering if it is worth it or if I should sell them and get some 225's. This is a street car that sees the track once or twice a year. Any info would be greatly appreciated. I'm sure i'll have more questions as I get into this further.

I read a post some were by Tony were a guy built a 402 I think and ran a set of 205's on it with very good results and it was a very mild cammed street car that made great power. Do a little digging and you will find it. I think they are fine on a 402. I think they did a little work to open up the chambers to un shroud the valves a little more.
I'm building a 383 and re using my afr 205's with a vc jr intake and 750 demon carb and T rex cam. I hope it will be pretty nasty!

402 w/ 205's is one potent little combination on the street. That is what my winter build is comprised of.
