at least 91 i would think you might be able to run 89 but you would just have to try it out and see. i know 91 would keep you away from detonation for sure though

lol i put premium in the stock bottom end i was just making sure it would be fine to run premium in the stroker motor. i just didnt know if 11.3 was going to be to high for it. i hope to get it tuned to run good on 91 though

10.5:1 is barely scratching the surface on what our engines can handle on pump gas thanks to the reverse cooling. There are a number of LT1s out there running around 12.0:1 and even higher.
