I have a 4500rpm non lock up installed in a 1988 camaro! It is behind a 355 with aprox 425HP. If I run the shifter in #3 position and not in the #3 lockup position, will I have to modify the trans to prevent oil flow to the converter for the lock up? In short, will this work like a 350Th in this shifter possition? Will this operate with out damage to the trans or the converter?
Let me know! Thank you!

I have contacted Coan Transmissions out of Kokomo Ind! I have a convertion kit coming! I can't beleave no one on this forum had an answer for me!

I believe you have to do something with the lockup valve in the front pump, there may be posts online. Also IIRC remove the check ball in the input shaft. Aside from that make sure you have a good secondary cooler if its street driven. That thing is going to generate serious heat!

A search would have got you your answer.
