Have had my 904 for over thirty years. Get your rebuild kit from A&A trans just south of Indy. 317-831-3066. Get the sprag kit and a few other of there custom mad parts and you can have a lighter, smaller trans that will take anything that 360 will hand out as long as you keep the oil cool. Have them send a catalog. I run high 12s with mine. 904 doesn't wast as much power as a 727. Talk to them before you buy your used transmission. They will answer your questions and not try to sell you something you don't need. They have complete 904, 727s. But consider the a, A518. It is a 727 with overdrive built in and you can get a locking converter for good gas mileage. Shop around. Have fun. The people at Turbo-Action are good too.
