motor is soft

when the motor is cool i can light up the rear tires for a *** 50 feet but after it warms up i am lucky if i can get them to spin at all. i have been tuning my ve tables and just about have avery thing around 126-130. i have a set of edelbrock shorties, a comp cam extreme energy cam 12-249-4 with .434 lift intake .444 exhaust and 206/212 deg at .05 this is on a 112 lsa and a holley tbi intake with the 670 on top with 65pph's in it. all on a 350.

would too small of a pump shot do this. if so what would a good place to start and how big of a step should i make when changing the pump shot.

Sounds like there is an issue with the AE. Since it seems to work ok cold try adding some more AE at high temps with the AE correction factor vs coolant table. MAybe about 5 or 10% around the temps that the motor has trouble and see if its the right direction to go in.

That factor is what the total AE is multiplied by once its all summed up. Id add it in around the areas that the motor normally operates at once warm.
