Almost finished with 500 stroker 6 pack build. I'm trying to decide what compression ratio to go with. The heads are eddy rpm's, the cam duration is .231/.239. From what I understand felpro gaskets can put me at 10.4:1 or 10.1:1.

Can someone tell me how much difference this will make and how risky it is running 10.4:1 with my setup??? It is mostly a street car and though I want power, I don't want to worry about overheating or detonation

 

If it is set up properly it will be fine on pump premium . Have you figured the squish area, valve to piston clearances, etc. I'm guessing those cam figures are at .050 lift. Talk to your engine builder !!!

 

i run 11:1 on my 440 and its all street. doesnt load up too bad with the 4.56 in the rear end. but def shutting it off at trains and such.
makes for a wicked stoplight hero
