89 5.3 MPT70 swap 11.9@121 first time out
#1
Here is a little something that We have been working on over the last 2 years. Big D finally shed the tranny demons and got it to the track. At 4300 lbs and a 2.1 60' it ran a 11.97 @ 121 foot braked and a soft launch. We need cal tracs before hitting it with the brake. Video is crappy but catches the end and the time.

15lbs @ 15* timing right now. Still the stock 5.3 internals. We are playing with diferent knock sensor setups right now. Until we get that working right we dont want to up it to much. We still havent launched off the trans brake yet. It builds 3-4 lbs foot barking it at the line where as the trans brake builds 9-10 lbs. I'm thinking that it will wheel hop off the brake at least until we get some cal tracs for it.
It is a little tight but we kept the plug change in mind when we built the log.
