I have an 89 vette,383,11:1 CR ,heads are Brodix RR200, ZZ9 roller cam and its set up for drag racing, ET streets 3:73's Mini Ram 700r4 10" converter.
The old set up with ported L98 heads,stock tuned port intake and small roller cam with 10 to 1 CR went 12:70's with a 1.75 60ft @106.5.
What should I expect for et's with the new motor.
1UKE, Is that compression ratio a calculated one? what is your cranking compression with the ZZ-9 cam? Do you intend to run race gas or an octane booster with that compression ratio? Just wondering, Sounds like a great set up.
