What gas do you run in a 70 LT1?

[Jeffro]

I have run pump gas, pump gas\b-32, pump gas\b-33 as well as straight B32 and B33 racing fuel in my 70 LT1. B-32 seem to be the best price\price preformance ratio.

I'd like to her comments from others on what they run.

Forgive my ignorance, but I dont' know what b-32/33 are. I just run premium pump gas in my lt-1 and it seems to go pretty good. But I have to search pretty hard for stations that sell it without ethenol. I have tried racing fuel a couple times but don't notice a big enough differance in performance to justify $3 per gallon.

93 or 94 will work fine. The 1970 LT1 is the last small block with any significant horsepower, rated at 370HP with 11-1 compression. After 1970, the 350`s quickly went downhill.
