It's mighty hard to beat the 385 series for power per dollar, power per pound, and durability per dollar. I can't believe some of numbers the low-buck combos the 385 Series forum guys put together. One guy out there got a complete iron headed CJ engine for $75 from some bone yard, swapped to a 460 crank, overbored it, threw in some cheap TRW pistons, a flat tappet cam, ported the heads, tossed on a victor and a dominator carb and viola, 625ft-lbs and 560rwhp. Total cost...a couple grand total! Holy moses, how do you argue with that...I think I paid more than that just for the heads on my engine.
