I am building a 93 formula with an lt1 for pure stock ihra and I am looking for some opinions on Torque converter and rear gear for that combination. As far as the converter, What stall range should I be in? RPM range of the engine is probally only 5500. Advantages, If any, of having the lockup disc in the converter. The transmission is a 4l60. What rear gear is suggested? I was thinking of a 4.10 or 4.56 with 28" tall tires. . Thanks

Another person is preparing a 93 Camaro on Class Racer. Bullet has a Pure Stock Cam and Spring Package that will pass tech. Even that it is about done by 6000rpm.. I am adding a Yank PT 4200 replacing my Yank SS3800 Converter. Since my car is driven to the meets they are locking converters. 4.65 gearing with 28 inch would work well. Would spend the money to get a complete Moser Rear. The small 7.5 inch rear is ok at stock power levels. Send pictures of your ride and will post it on the PhotoGallery. Dan |

The '93 has a removable chip. You would also need a device programmer, and eraser.

I guess the way I am reading the website, It comes as a package with the burner, Tuner program, and everything that is needed.

I'd speak to the man Ed Wright who posted above.
He is very knowledgeable from what I have read here. |

They may very well have a package like that.

Rule book is unclear about rear suspension. Are we allowed to replace the lower control arms and the the track locator bar with aftermarket? And What about Frame connectors ? Also the torque arm. I want it off of the rear of the trans. Are we allowed to build a support for that as long as it is part of the trans crossmember? ? I know I saw a 70s camaro with slapper bars at Norwalk a few years ago so I would assume you can use them for Leaf springs. Thanks Aaron
