It would have to be the supra for power production, but for longevity, I still vote for the 235 chevy. How many 40's and 50's chevy's do you see on ebay that say, "Pulled car out of swamp/barn/lake/haystack/tree stand, poured gas in carburetor, and it fired right up and runs like a top?" The only reason I haven't put the supra engine in my 56 yet is it just runs so **** good, and I can't find it in my heart to pull a perfectly running engine.
