Hey Sideways, the only dumb question is the one you don't ask(that's the way I feel anyway) As far as I am concerned, if you don't run a cooler on turbo 350, you're asking for trouble, I came close to cooking a 350 because I didn't run a cooler. I run my cooler lines thru the radiator and have no trouble with it. A small cooler is definately better than nothing at all. As far as getting a driveshaft for your tranny. I would think that a salvage yard could cut and weld one together the right length for you if they know what they are doing.

what type rear end are you running?if you have access to a welder you can do it yourself just take a angle grinder and grind down the weld on the back of the driveshaft where the yoke is welded on and the whole thing comes off then just messure how long you need it i usealy put the yoke in the tranny and leave it out about 1/2inch then put your rear ujont and yoke in and messure to where the old weld was. then burn it make sure the yoke is put back in the way it came out and then have it spin balanced hope this helps i run a nova rear end in my metric car with a short shaft 350 and a nova shaft fits fine stock

i would run a small after market cooler. mount it on your rollcage on the right side, put the top of the cooler even with the dash. this will let it get air and keep most of the mud off of might want to build some sort of shield to keep oil off of you in case a line breaks.

Most definately run acooler of some kind.In my experience I have found that a standard 3-speed tranny was the way to go.Do you have to run an automatic? If it is a matter of personal choice then by all means find a cooler for it.I have seen numerous mounting positions for these.Inside,outside, under basically anywhere.The best way to figure out where to mount it in your car is to look at the inside after a heat race or hotlaps when the track is still flinging alot of mud.Look where the least amount of mud is inside the car and go from there.Nate is right about coming up with some kind of barrier between you and all that hot tranny fluid too.That would make for a really bad night to get soaked with that stuff!As far as the drive shaft,you can more than likely find one that will fit without cutting and welding on one.One less weld in the drive train means one less chance of a failure to me. Let us know what you did ok?

HobbyStocker is right. If it is legal try running a manual 3 speed, it won't disapoint you I promise.

Rules say automatic with working 11"torque converter.If that were the case it would be a standard tranny.The differece in the two trannys (length wise) is 3 1/8".So my drive shaft needs to be that much shorter.Thanks for the help guys!!!!!! By the way it is stock rear axle racer17j.
