Guys,

I've had several people tell me that the ideal drive angle for my combination....4L60E and C4 IRS would be between 2.5 and 3 degrees. The rear end wont be any problem....but darn if the transmission is close enough. I'm at 5 degrees. I cant raise the transmission any more....and cant lower the motor without notching the top of the frame (A/C clearance). I really dont want to go with a different pulley system. I know to angle the rearend pinion at 5 degrees opposite of the transmission so theyre center lines are parrallel. No problem there. But.....do you see any drive line problems down the road for me? I'm not going to mind replacing u-joints....but just wanted some thoughts before I commit to finish mounting the rear end.

Also, I think I found the answer by doing a search but I still want to ask. I plan on cooling the transmission with nothing but a pair of dual pass 18" heat sink style coolers from Jegs. Think it will be suffient enough? I'll be placing them on the inside of the frame rails....away from the exhaust. My exhaust is going to be under the running boards....of all places. There actually is plenty of room.

Thanks,
Dave
