4gc carb

Jim Hanig · 09-02-2013, 06:55 PM

Anyone care to share the trick to make this carb work in a wheel stand.? I have tryed most every thing more fuel pressure 13# and down to 9# 5 degrees to 10. open spacers 4 hole 1 inch to 13/4 all i can get under the hood .If I tie the car down then it spins. Will do it off the ft brake or trans brake, SMALL BLK 327 250HP. 3200lbs 5.38 2.52 92 inch 10.5 raidail tHE ENGINE JUST QUITS IN THE MIDDLE OF THE Wheel stand drops like a ton bricks . So far 1 broken trans case 1 broken oil pan. 1 bent set of headers. I have limters on the ft and wheelie bars. Its not the wheel stand just that the motor quits. A small holley it goes right down the track. I have 2 carbs 1 Deno 1 Prc they both do it. Help.

Retard the timing on launch. Doing so, you might run faster with just the timing retarded and / or the front tied down. The cheapest / easiest solution that pops up in my pea brain.

Jim,

Call me if you want to talk about this again. Have you tried everything we discussed previously? If this is a carb problem, we can solve it.

I run a Deano 4gc with a heads up spacer. 7 psi leaving at 9000 in the air never a problem. This is the angle spacer. I was told you cant run a flat spacer with a 4gc.
