It wouldn't qualify as a Gasser to run in any Gas class because the front end is way too high. Gas class rules call for the body to remain level, in spite of all these sky high front ends you see on "gasser" models. See the rules under "Body." You could get away with SOME added height in the front but not that much. Also, the engine crankshaft centerline was limited to be no more than 24" above the ground. In 1/25th scale that would be one inch. See "Engine." Has to have a hood. Also doesn't have any inner fenderwells...had to have them too with any fenderwell header openings being no more than 2" away from the header tubes. See "Fender Splash Pans."
If you are really interested in building a "legal" gasser, here are the rulebook pages from a 1970 NHRA rulebook for the Gas classes.... I have the entire rulebook posted on my Fotki site here....http://public.fotki....nhra-rulebooks/ Hope this helps you!
