383 fine tuning
I got the 383 in the vette and it is running. Just seems that I have no bottom end, really sluggish. Kinda disappointed thinking that I might have made a mistake. Don't know what to do now.

This the motor I put in, the cam is a Howard part number, 110265-10, it has a bbk 58 mm throttle body, eledebrock hi flow intake and high flow runners, I had Scott Hansen reprogram the computer. 26 lbs injectors, fuel pressure is at 44 psi with the vacuumed unhooked, timing is set at 7 degrees, and tps is set at .60 millivolts.

Lots of info missing but I would look at the timing first.Sounds kinda low to me.I would think it would take more initial than 7 and what is the total advance.
Did you get a dyno sheet with yours?If so post it up so it can be critiqued.

Totally agree, you need more timing at idle, more like 12+ I would guess, there may be other things but that is pretty much a given on the initial timing. Talk to your tuner. Good luck, you will get it worked out.
