LS6 Coupe

A note on the converter. I've tried both ways (more and less stall), and the factory converter actually does seem to be about right...on the skinny tires. On stickies it's a different story. I don't know if Pete has done any experimenting with stall speed, but we had trans troubles the past couple of years, so had several opportunities to try different converters. Too tight, and it's lazy out of the hole...too loose, and it simply blows the tires away. So, Petey, is any of this close?

As for the superceded castings, you're supposed to have the right parts per your application (or supposed to anyway). Remember, if you don't certify, the 99% of the tech is done on the honesty policy, unless you are one of the unfortunate ones that gets to pull a valve cover. Some people stretch the rules, others don't.

Whatever you decide, built it for Pure Stock and come play with us!
