Currently a blast to drive but I want to try dial in the whole system even more, wondering of the 373 are just too mellow for what this combo needs? sometimes at part throttle acceleration it seems a little sluggish.. id like more instant snap if that makes sense..

Currently have 373, and its nice, but i wan to push the street factor the the limit - the 383 doesnt always have the brute low end of the big bocks, so some mods are necessary.

Cam is around 2000-6000 236° / 242°, 288° / 294°, 11:1 (installed straight up), 200/64cc alu heads, 5.7 rods. 850 dbl pumper brawler, Vic JR, 1-3/4 LT headers into 3 inch collector and 2.5 true duals. 373 posi, 2004R, 3k stall..

18-20 initial, vac adv disconnected .. Hei stock.

Ok - I had mine rebuilt at art carr in Huntington beach 200 miles back- so far ive been happy but not sure if a better one will make that much of a difference? Im going to try a 750 and see if the performance increases..

higher stall or lower? currently 3200

Look at optimising what you have first. I'd be looking at a better convertor.

I'll probably grab a set of 4.10s as well and compare down the road-

With 4.56:
65mph rpm is 2400rpm.
125mph est trap speed 1/4 mile its 4585rpm

4.10
65mph = 2150rpm
125 mph= 4250rpm

373:
65mph = 1950rpm
125 mph= 3750rpm

Hi, yes have limited the hei vac adv long time ago with bushing and stop screw. Good info. I did buy upgraded parts from art carr.. I'll look into the sm465, and maybe 4L80e.. down the road. Good answers thanks folks
