I'm planning to run my new 383 at the track on Friday and I'm debating on what to run for fuel. The engine cranks 200 PSI. I've been running 94 on the street with no apparent problems, but I'm a little concerned about the 94 at the track. I'm considering mixing 110 half and half with the 94 to give me 102. Any thoughts or recommendations?

I think 102 would be more than enough. I crank 220PSI, and that's what I use. One the street, I'd go for 25% 110 and step it up to 50% for the track. There are, however, people running on the Chevelle and Camaro boards with about 200PSI and still run on premium gas. You may be safe with 94 if you run aluminum heads, but I personally don't take risks on $$$$.00 engines.
