So i just got a new engine and trans going and so far its pretty good but im having trouble with the fine tuning. Th350 and 350 mild head work, cam 230/230 @50, rpm intake, msd hei, edelbrock 1406, 2000 stall(b&m holeshot).

Over 3500k it hauls and putting around its ok but give it too much gas and get into the secondaries and it bogs or stumbles then starts to pick up.

About 14.5vac at 850-900rpm

Timing is 25 initial 35 total

Adjusting the shot on the accelerator pump doesnt seem to make much difference, it sprays great though and starts as soon as you touch it.
.95 secondaries .98 main jets .70 x .37 rods. Leaned out or like this the bog is still there but its better now that i richened it. Still wont spin the tires, ive had half dead 350s that would spin the tires..

Any help is much appreciated
