Took car to the track after putting in a 2200-2600 stall. The car still bogs out the hole and only picked up 1 tenth. My car is mostly stock, so how big a stall do I need? It weighs about 3200 with driver
2200 is not much looser than a stock converter. Your intake, t/b, etc... are not helping much with those stock E7 heads. They cost you a little bottom end tq.
I would think a 3000-3200 stall would be best, with the stock heads and once you put some better heads on it will still be good.
What size rear tires are you running? If the tires are too big, it will also kill the launch. A 275/50 drag radial would be plenty and would be around 25-25.5" tall. You should be running mid to high 13s if you get it ironed out.
Maybe try bumping your fuel pressure a couple psi and bump the timing another couple degrees, or perhaps remove the spout and lock the timing out at 32 degrees.

Thanks Mr Blue! ok maybe 4.30's, heavy old gal needs some motivation! seriously, more gear and stall should help get her moving. i know it's a street car, but how about a diet! search the weight reduction threads on here to get some ideas.
my street tires are 245/50-16s and track runs are 255/50-16s MT DR. I have a friend that is going to swap rearends with me, he has 3.73s. I dont want to go to 4.10s because it will lose some streetability, I drive the car to track that is 40 miles away and I do plan on cahnging the heads. My goal is 12.99 with the stock heads.
