Not sure if this is the correct area or if advanced tech is better but how hard is it to convert to race fuel?

Well I bought a second Camaro that I'm going to use for just the track that's why I was wondering the highest octane down here is 91 also

you can run unleaded race gas, or low lead without changing much... but again you dont really need it unless your running a power adder, or high compression.

Hmmm ok guess I'll stick with the 91 octane here and I'm not running cats on either car and o2s aren't to hard to change

I can run 91 in my car without ping or knock. Compression is 11.3. I run 93 when it's really hot out though.

Well while building the car for STRICTLY for the track, highly consider the fuel and what your willing to spend. Every fuel has advantages disadvantages.
On a NA build lean towards a oxygenated fuel. Q16 makes good power but has MTBE in it and is harsh big time on fuel systems, E85 is oxygenated and makes good power, is dirt cheap, but has to be drained every couple months if it sits cause it attracts moisture and the moisture will eat fuel systems.
If you're just looking at a mild build in the 12ish region for static compression pump gas 93 will work, your cooling system, TUNING, and how much cylinder pressure you make based off the split in the cam, cam timing, ring selection, etc. I ran 93 on a 12.9 almost 13:1 motor but I switched to E85 and am looking forward to.hopefully some good results, or at least my tuner thinks so lol.
