So did you ever figure out what causd your #7 rod failure on your 2nd motor? Those were aftermarket rods and pistons with that stroker kit right?

Basically it ended up that quench was too tight, and there were a few times where I was in the top of 3rd and ended up in 2nd instead of 4th...from what I could tell I never went higher than 7K but who knows. I did this quite a few times trying to get the shifter figured out. When it let go, it had been months since it happened. It's the only explanation my machinist could come up with. Rods were Scat I-Beams and pistons were Mahle. I'm running K1 H-Beams and Mahles in the latest build.

Aghhhh yes, I have read that mis-shifts are the #1 death of LSx's besides the dreaded oil starvation from the stock F-body pan on track event days.
You are lucky you got away with it a couple of times.

I feel you on the shifter....the damn shift gates on the T-56 are DAMN close....too close for comfort if you are required to shift/downshift with urgency and percision

You ever install an accusump or did you mod the pan?

Anyway, good job man...I wish I was near you. I would love a ride in that thing.

I never went with a Accusump and I'm running a modified F-Body pan. Just kept it overfilled a tad. My crappy welding and the high zinc content of the stock pan finally bit me in the ass, the pan started leaking bad after the recent build. I grinded down the beads and put some JB Weld on the pan to try to fix the slight seepage I was getting before. So I ordered up a custom pan from V8 Roadsters that has trap doors for the pickup so there's no starvation...also its 7 quarts, it uses a remote filter. Its gonna be here Tuesday, I'll post some picture up.

Just with the crank hitting the pan.
