who knows 4 speeds?

Two things, first there were some 273/slant six trannys (not those O/D units mind you) with a 3.09 first gear. I had one in my car, it worked fine but it's just too brutal. Secondly if it's bogging you need to launch at wide open throttle. Do you have a rev limiter on it? Set it up about 200 rpm's above your shift speed and below your max engine rpm and that's what you leave at. This will probably break parts, but then where would the fun be in not breaking something now and then?
