8 3/4 gears

That's really a loaded question. Just going from 2.93 gears to 3.23 gears isn't much of a change. If your right on the virge of being able to smoke them right now but can't quite do it I'd say yes but if not I'd say no. A stock 318 in 68 had 230 hp and was a decent running engine but no powerhouse with it's tiny 2 barrell carb and generally single exhaust. Hopefully your running a 904 trans or 4 spd. The 727 will suck power away from your already under-powered engine. To answer your question there's only one way to find out. Put it in and let us know.
