Thanks for all the advise. I will print it all out and show it to my racecar mechanic. The distributor is orignal one. The block was the only thing my father had to change out. I found a list of pure gas (without enthanol). The highest octane rating was 93. I tried the tetraethyl before but it didn't seem to improve the performance. That might have be due to the really bad job the people that originally restore the engine. I will give it another try. I will also look up the info on the vitameter. Thanks again...Don
