Re: rear gears

I don't know your entire combo, but from the little you have posted that is wayyy too much for your current combo, even with an OD automatic or a 5 speed manual, just consider 3.42 or 3.73s max for some added kick in the pants from the gate, but you will soon run out of breath with your factory TPI system IMO.

Zoom or Richmond have never let me down as far as manufacturers for gears, but you could consider Jegs brand gears at your H.P. rating for now.

Dude you have a bored 350 with who knows what else, and he seems to have a stock 305 with Tuned Port Injection no less, he's running out of breath with what he has with factory gearing above 5,000rpms....
