HP & TQ difference between 10.1 comp to 11.1 comp?

With nothing else changing you might not see much. Both of my 440's were a static 10.5:1. Both ran/run on 92+ pump swill.

IF you up compression the cam needs to be adjusted to that new compression as well as other items if needed. Look at the compression ratios in modern performance engines. They aren't low.

2015 Camaro 11:1
Challenger 10.9:1
S2000 11.1:1
GT350 10.3:1

Hellcat 9.5:1
GT500 9:1


Nor are they comparable to dinosaur engines with no quench, no squish, no EFI and nothing else to aid in combating detonation. Bad comparison.
