Agreed. I like to drive what I have. Besides the enjoyment factor, helps keep the old iron running fine. I have done the adding race gas to pump gas many times in the past. Just a hassle sometimes, and then ethanol mixed stuff at the pump is a different story altogether. Lots of other cars are more than fine with running on premium, but most guys seem to want the loudest and the fastest car at the cruise lol.
The real variables in this discussion are elevation, air temps, inlet air temps, ignition curve, plug heat range, load and speed. If you are just cruising, 93 is probably fine.
Now, if your in Phoenix or Vegas, running the car hard, in 110 degree heat, maybe mix it to 95-97.
Don’t mix leaded race gas for use on the street. They look down upon such activities…
True, you are technically correct. However 99.9% of enthusiasts wouldn't know the difference and these cars are generally embraced as "muscle cars" even if they don't meet the original terminology.
Agreed. I have bought a few cars with the repro bias belted red lines and polyglas tires on them and couldnt wait to get them off for a set of basic BF Radial T/As. You can actually drive the car then.
A rather broad brush with which to paint.
A 64-87 GM intermediate with radials, modern shocks, and non-worn components are quite well engineered and aren’t a buck-board by comparison.
To compare apples and apples, I’ve driven W-body V8 cars, and they aren’t really enjoyable.
