if you ever want to run on pump gas i would reccomend moving the compression to low9's as long as you keep your boost under say 12psi

Probably 10-12psi on pump gas and higher on race fuel.

9.75:1 and 10 - 12 psi on pump gas does not sound like a realistic combination, but maybe someone can give a real life example.

This
ATI F1R
would go in this
1999 Corvette Coupe
?

Are you sure it’ll even fit? C5 engine bays aren’t exactly spacious and fitting an F1R in an F-car frame isn’t easy w/o some frame cutting. Best of luck. Sounds like a vicious combo. I'd consider a CR around 8.7 or so if you want to really stretch out that F1R.

i am in agreement with the others that you should try for lower CR.
"I" would go with the 9/16 head stud aswell
you can't go wrong with what TEA offers in there stage 3 6.0l head the number are totaly awesome.
save the money on the pullies and go right to Cogs if you can.
F1R might be a little over kill for the ci but if you got a big cam do it up.
are you going Solid or Hydro?

if you are only going to run 10-12 then the F1-R is a waste of money.
