Need some help dipping into the 11's

I agree with 70aarcuda, that thing should be hauling. I would start by making sure your timing is set in the right ball park (34° ish), then jet for best MPH. More converter would be a step in the right direction as well (without knowing cam specs I can't say for sure, but your 3k stall is probably way too tight).....but seeing that you can do 112 in the 1/4 tells me that you should be able to get a 11.9x as is.
