Once upon a time in the 80's, I put an L-20B in a 620 PU that originally came with a 1600. I used a 240Z flywheel, which weighs about 5 or 7 pounds less(can't remember exactly how much) than the stock L-20 unit with a B-type 4 speed. That thing would rev like crazy.

The most powerful L-20B I knew of was one built by Frank Honsowetz in the early 90's. It put out 215 HP with the power band starting at 6000. It has the later FIA cylinder head and the twin 50mm Solexes. It's still around, but hasn't run in about 15 years. No nitrous, nitro, alcohol, or other BS, just race gas like everybody else was using at the time.
