904??

titanium said

I want to use mine. I bought a rebuilt 72 340(steel crank)and was just thinking that if I had another 904 I could just bolt it up to my new motor and take my motor/tranny out and put the new motor/tranny in. Hoping all in one afternoon. Figured it prob. would not work. Can any one recommend a good convertor and rebuild kit for those 904's? The 340 I have is pretty much a stock rebuild. The kit I was looking at was from Mancini(part # MREBMM904886). Not sure though.

Since your swapping to a newer engine you do need to swap to a 68 or newer 904 due to what Locomotion mentioned about the size of the register (snout) that slips into the crank. That size changed in 68. Just make sure you don't get a lockup trans. You can identify them easily by looking at the input shaft. If the first 3/8~1/2" of it is machined smooth it's a lockup trans. If the splines go all the way to the end it's a non lockup. I've used PTC converters with good results but there are several other manufacturers out there making good ones as well. Turbo Action, Ultimate, Dynamic, just to name a few. A good quality converter will cost you more than an off the shelf part but it'll perform better. Check out Trans Star rebuild kits. They are the same parts that Mancini (and others) repackage into their boxes and charge more for. Northern Auto parts has good prices on them. Also check into installing a Trans-go TF-1 or TF-2 shift improver kit. It'll make the trans. last a lot longer and work better.
