with the transmission you have now that might be the problem. have you tried running it shifting it manually. i found that in my truck with a 305 it would haul *** only if i shifted manually because it shifted too soon otherwise and i was losing power. then there is always increasing cam size and adding a stall convertor but then again i would just change the tranny over to a th350 or th400. with everything you have on your engine it shouldnt be too far away from 300.

I dont know what the weight difference is in the two cars, but a comp xe268h cam and a performer RPM intake would make a good 350 hp. The vortec heads are a superior design to the double humps. Seeing as how you already have the intake, you are on your way. A set of heddman 1 5/8 " headers are also a cheap idea. Also, since you have an overdrive tranny, I would throw a set of 4.10 gears in it.
