Those heads are holding you back. Headers could probably use an upgrade as well, but they've been in the 12s many many times. You really aren't benefitting from the super ram by keeping those stock heads. A ported tpi system may produce similar numbers (maybe a bit lower on power but more torque). Very nice looking car, though. Got a shot from the side(with those rims)?

BuckeyeROC's car went 12.1@112 with a nearly identical setup. I know 'cause I built it. The only difference is that he has the AFR 58cc straight plug heads and is running basically the ARAP .bin with 40 degrees total advance. Plus he and his car weigh a lot more. I vote the AFR 58cc's

My best so far is 13.7 @ 102.
That's with a failing fuel pump and little tuning.

I'm hoping to change that soon.

Yeah, I second the AFR 190's. Your heads are definitely holding you back. Lingenfelter uses ported alum Vette heads with much success, but he might charge enough that you could get some AFR's instead.

Take off about 15hp and 15tq for the stick and another 20hp and 20tq for the cube difference. That puts you at about 333rwhp and 390 rwtq. That's about what you'll gain with a set of AFR 190's. Gaining 60+rwhp and 90+rwtq isn't that bad for just a head swap, is it? BuckeyeRoc is probably putting the #'s I figured about to the wheels and he's running 12.1's at 112mph w/ your combo, the only difference being the heads.
