thats a 10cc dish? i mean fill me in on what specks you're using exactly for everything you used as input. looks to me like with a 10cc dish that gives . and about you just about stock compression and an 8.37 dcr. which should probably be just fine on an lt1.

 

sorry bout that, yeah thats a dish. i dont want to go too crazy with it unless you really think i can get away with more. id like to make as much power with it as i can but i dont want to have problems. oh and 1 more question, how do i determine how high a piston will sit in the bore without actually sticking it in there? is there some formula for that? thanks for your help -dave

 

The CC's fastfatboy was referring to were 6CC valve reliefs not a dish. You can have Probe make you a 8CC valve relief flat top piston with no dish.2 eyebrow instead of 4,niiicce flat top.

You should be real safe at 8.7 or below.

Some I have talked to claim 9.6 on the street and pump gas??????
I don't want to go there!!!!!

You have to assemble a hole on each corner and measure it to see about your deck height.

 

Chuck talked about a 10.3:1 DCR Pump gas motor! Scary.

 

I ain't brave enough to go there.Can't afford fuel for the street.
Gas prices keep going up it won't matter.

 

Tell me about it.... I'm about to dump Evans in the SS just so I can run 87 octane... Hell it's only 10.1:1 now with a stock cam should have a nice low DCR anyways.
