Re: 408 Stroker Combination

It looks good but it would be better to know what vehicle you are putting it in AND the usage? What are you goals???

Re: 408 Stroker Combination

Looks like a lot of cam for what appears to be fairly low compression to me.


My -4cc AFR185's with the same dish is putting me around 10.8:1 I believe so what is your static compression ratio?

Re: 408 Stroker Combination

Yeah, need way more info including gears, trans and stall if you use an auto.

I would use a higher lift cam or 1.7 rockers with that cam with that engine and those killer heads.

Also, exhaust size is important.

Your static comp is around 10.0

It will make well over 500 hp that is for certain.

Re: 408 Stroker Combination

klaw64 did you ever build this motor? I'm wondering what combination you ended up going with. I will be using the Comp cams Extreme Energy XR288RF-HR cam in my 408w. Wondering if you went with it and how you like it.
