Compression will be at about 13.6 to 1 with .040 quench.
Will be running on E85. Cam is solid roller street grind 267/279 .640 lift.
Heads are EZ'z with MCH cnc porting.
Also will be running HP EFI system. I think this should make a nice street engine, I would think 650hp shouldn't be an issue.


I suppose I could get the .036 gaskets, maybe that would be the way to go ($450 laying around in head gaskets, ouch).
I'll still ponder on it, thanks for all the replies so far!
