The best all-around engine for a budget-minded guy is a late model, roller-cam, Vortec head 383 with an upgraded cam, dual-plane aftermarket intake, 650 cfm vacuum-secondary carb, HEI and headers. A smart guy can make a killer pull-out buy on one of these and be on the road cheap...and make 400+ HP.
In terms of power per dollar...it's impossible to beat
If money is no object...a supercharged LS
