Since we are on the subject... Are belt drives worth any measurable horsepower or is the benefit more or less reduced valvetrain harmonics?

People like Grumpy Jenkins felt there was which is why he ran a Nylon Gear set-up in his Pro Stock Vega years ago. Grumpy did stuff for a reason.

Measurable? Only Jenkins would have known the answer to that deal.

Reduced Valvetrain harmonics? Would be high on my list as a possible reason.

That would be the main benefit in my opinion.

Ease of advancing/retarding the cam is a big plus to me. Good hp gains can be found there that most never see because of the work involved to do it normally.
