USE- 3400# car w full tank and my fat a-- ,Mostly street cruising runs to shows + cruises (up to 100 mi's) ,no daily driving. Never see drag racing (except from the parking lot). pump gas and low grade at that.I fully admit alot of this is overkill but i had it and I FIRMLY believe in using up (or at least trying) what I have B4 spending more $$$.
I am fully aware that more can be done in the head/cam area's for bigger HP, but I think it is overkill for my use, The block as I said was done B4 for a drag car that never happened. Detuned + rebalanced for street use (sold the 7 1/16 bolt dimple rods, 13:1 forged pistons and square ports), but the bottom is SOLID for over my RPM range.

Anyone hazzard a guess to power numbers??? Which carb is better suited to this combo-Edelbrock 750 man. choke
