So, what do owners do who readily drop hundreds of thousands of dollars on original high performance muscle cars like Hemi Cudas, 427/435 Vettes and such at auctions? They seem to run fine across the auction block. Do all owners fill up at the airport to be able to enjoy their expensive rides! That includes owners of survivor hi-perf rides. I don’t consider this to be a dumb question! If I need to significantly detune my build it may not be worth it to me. If racing or airplane fuel is what I need to run I have no problem with that.
I’d appreciate more input on this. Thanks, John

I have a low mileage original 70 Z28 with 11:1 compression , and I drive it monthly when weather permits. I have run straight 100 LL from the local airport for over 20 years and the Car loves it ! I usually pay $5.00-$5.50 a gallon . I know not every body live 5 minutes from a airport ,but my Z is almost un driveable on 93 pump gas
