Its time to upgrade and make more power so ive been considering selling my current engine minus acc and tb, trans with converter, and rear diff all as a package deal to make someone a 12.0 package

Engine is LS1 with 243's milled .012-.015 and .040 cometics, TSP 228r-112 cam, pushrods from TSP and some .650 lift springs, LS6 sodium valves, pacesetter 1-3/4" LT's, Ported Fast 90 intake, and LS6 injectors, Volant cold air intake with custom ram air for 03+
Trans is stock with shift kit, vette servo, billet OD servo, TCI 9.5" 3600 stall, starting to slip and will need a rebuild
Rear diff is 05 with druns, detroit trutrac, and 4.88's, stock axles

Im just not sure what to ask for it all

 

How many miles on the engine? Any upgrades on the internals? Oil pump, rod bolts or anything. I'm in Texas and might be interested in it.

 

50-55k on the engine all stock other than when i got it i had a fresh hone and rings fit. Shift points at 6400 for WOT.

 

Went 12.27 @ 109 letting all the way off the throttle to let the trans shift 2-3 then getting back in it. Easily a 12.0 pass if trans would have done right. DA at the passes we made was 1100-1200

Trans isnt slipping its just not making the 2-3 shift at the track. It works like it should once home on the same drag wheel setup. Not sure whats happening here
