Some emailers ask if these Harrison engines used nitromethane to any great degree and if it was a factor where records were attempted or set? The answer is from me that I don't have a clue. If anyone does, please feel free to fill us all in.
The Harrison's cousin the Anzani had a cast iron block that could take severe nitromethane loads to a point but the Harrison had better rods and crankshaft technology in an aluminum block with ferrous sleeves which in the 350s even had 4 more head bolts. There must be quite a few stories out there on what was done and the results they obtained?
