setup consits of 218/222 581/569 on 114 cam, mild ported heads, tnt nitrous kit should be at around 150 shot
9 inch with 3:70's car is easily around 3600 pounds

i have a ptc 3500 stall, but i can foot brake it all the way up to around 3400, so i think it may be a little to big for my app. can anyone help me out?

 

spray it and see where it goes. From there you can decide if it is too big.

 

I'd send the PTC converter back and get it restalled. Kenny does a pretty good job on his converters. If you're footbraking 3400, then it's flashing alot higher. Do like Ragtop suggested and see where it flashes on N2O. I'd like to see a flash stall of no more than 4000 on motor and no more than 5000 on juice, preferably a couple hundred less than that...those TNT kits hit pretty hard.
