Can I run leaded race fuel?

I was just wondering if I could run a leaded race fuel. I don't have O2 sensor or cat converters. I don't have to worry about emissions testing. Let me know something. And if I can't run a leaded race fuel, what would be a good unleaded race fuel to use? Thanks.

if your car is fuel injected. i would think it would cause damage to your injectors. get some turbo blue

Re: Can I run leaded race fuel?

why do you feel the need to run race fuel on your 305 tbi engine? Extra octane won't do anything for you other than lightening your wallet.

Really the only thing that lead would hurt would have been your cat.

Re: Can I run leaded race fuel?

Sorry, I need to update my sig. I lost my car to a friend, so I had to put all my new parts into a 1982 Silverado. It's a cammed 6.0 with boltons and a 175shot of nitrous. It's carbureted. I am planning to start selling race fuel out of my nitrous shop, but I figured I'd try some different types first. I do have a tuner who uses a wideband and a dyno to tune.

unless it has high compression, there is no reason to use it at all.
