Re: I need advice (c4)
What area are you in?
At 18 psi on a 347 you are getting an honest 800hp at the rear wheels so you need to have the advantage of 7 clutches in the forward pack, 6 clutches in the direct pack, teflon sealing rings, 180 - 200 psi line pressure and (I hate to say it) carbon and Kevlar linings throughout. You also need about 60000 pound (towing capacity) cooler and a host of other mods to the case, pump and stator support.
Since the C4 that you have was built for 550 HP and you have nearly doubled that now - you simply need a transmission that will work with that much power.
