Figured I would drop in and update the build a little bit.
Before I pulled it apart, I replaced the huge intake with a stock truck intake and replaced the worn out slicks with a 255 et radial and got the car to some pretty consistent 7.9's with a 1.7x 60'. After that I got some 3.5" front runners, Moroso trick front springs and put in a smaller cam (224/230 114). The car picked up a TON of torque and I don't feel it lost anything before my shift point.
As a side note with the nitrous, the car only got one track outing and that was on the old worn out slick and stock shock setup. with low bottle pressure and 10* pulled the car only picked up from 12.5 to 11.9 on a 150 shot lol. lined out with the radials, shocks, springs, smaller cam and intake i really feel the car could have went basement 11's if not a 10.99.
UNFORTUNATELY, I didn't get back to the track with the new setup. A valuable lesson for all LS swap guys... Don't use the truck pan! Slowed to about 40 in a construction zone (55mph) and still dipped down and ripped the pan off on a bridge lip with my wife in the car. almost lost it with the oil under the car (and her clutching my right arm). Happened on July 4th on the way to a family cook out.
After pulling the busted pan motor to swap out the oil pan, I noticed the bell housing on my PTC th400 was cracked so I went thru some dark days and gutted the whole setup lol. Going to put a JW bell on the trans, a fbody pan on the motor and use it in my wife's mustang swap.
The new setup will be an aluminum, square port headed 6.0 (l76 from a G8 GT) with a big cam, big converter in a pro braked 'glide, and a 29.5" tire on two kits (150 progressive and 100 on a short ramp). I plan on running this car in a local no prep/ no time series so there may not be any time slips posted once it gets up (i expect April time frame).
