Late Model Racecraft

It's almost like every car coming into the shop lately wants to build a 900+ rear wheel car. This customer was no exception. This is a 2016 stingray with 8 speed auto.

Build highlights consist of:

• LMR drop in pistons
• LMR custom DOD delete cam
• LMR cylinder heads
• Procharger F1A
• LMR low side fuel system
• Dual nozzle meth

We are starting to love the drop in piston idea. Can throw a bunch of boost at them and maintain stock compression

Give us a call at the shop for more details! More similar builds coming!

He's going to need some new wheels and tires on that thing to use any of that power!

What is your opinion on the drop-in piston (base stingray) vs. Piston/Rod combo on LT4 shortblock?

Late Model Racecraft

We love them. So far we have made as much as 953 RWHP with the drop in pistons. And that was with the filter still on the supercharger. Now what we do not know is how strong the stock connecting rods are. We have yet to break any.

Late Model Racecraft

On the LT4 pistons and rods, we have made over 1000RWHP and had no issues. We have yet to break an LT4 Rod or piston.

And the stock 8 speed can handle this much power?

So far they are! Some have broke. Some are hero's. Some die hero's.

Late Model Racecraft

With any High HP build drivetrain components get tested. Some of our customers who race these applications on a weekly basis have had trans/torque converter issues while others are still running strong in factory trim.

I can’t get my 671 whp 8 speed auto to shift into second gear if I dead hook it. If I cut a 1.7 or slower 60 ft it shifts great , Any ideas? The tuner said he had no idea what the problem was

Late Model Racecraft

Are you still running the factory trans and torque converter? What about rear tire size?

COALMINER,KY

yes stock trans and converter. The tires are mickey Thompson et street s/s 325/30/19 which are the same diameter as the stock ones. The mickeys are just way wider

Send it to Steven to tune!

COALMINER,KY

who is Steven ?lol, even when the tuner set the trans to shift at 19 mph it still wouldn’t shift, and reved out in first gear

Late Model Racecraft

Feel free to pm if you would like. Curious how much your tuner has played with trans tables....shift pressure, shift time, TCC, etc etc.....

Steven is who is chatting with you on this thread from LMR. He’s the owner / tuner at LMR.
