I believe that a big leap was made in nitro performance, back in the '80s when in fact the top alky guys went nitro racing, as mentioned: Tim Richards, Veney, Armstrong, etc., and Steve Boggs knows his way around a fuel motor. But, I don't believe that leap is there anymore. As a driver, I'm sure Frank could get comfortable fairly quickly. As a tuner, same thing I think. If he ever releases the butterfly for good, he could probably make a great living as a tuner (alky or fuel). Seems like he's enjoying himself though, and I think he's late '50s, so he's got a lot of time.
