CWR stroker thread. 460cc engine.

[jasonp]

Greg runs 12.5:1 compression with his 460cc stroker kit and says it will run off premium pump gas 93 or better.
A 89mm bore with a 74mm stroke. So, 9.5mm more stroke and 6mm more bore. Wow. Impressive. Same as Powroll as far as stroke goes but has a much bigger bore. I wonder how he gets away with that.

Theres the thread and I just asked him if they shorten the rod or use a spacer plate.
Mickey still has more stroke.

Info on a shrunk rod.

So CWR doesn't use the shrunk rod like I've heard. Well Gregs kit seems it will give you Higher RPM power were Mickeys will give more midrange. It's probably a toss up then both kits look good. And make the same HP.

Mickey still has the stroker edge. I'll agree with you dave.. Mickeys kit will produce a much broader band of power where Greg's kit is more peaky I would say. Both look to be great kits. I can't believe Greg can get away with that much compression on pump gas. Interesting.
With that cam that you got though dave.. IMO, look the F out. It's bigger then CWR or FST sells and more CC's then Powroll.

I told it in an other thread you can run as high as 12,7:1 compression on premium pump gas 93 + ........ and by the way one of my teacher can sell me airplane gas 99-100 octane for 2$ can/L is it a fair deal ???

Try that on a 350 chevy with steel heads and see how that works for you.
Like I said before it all comes down to the design of the engine/head etc.
