Hello, I am Paul. This is my first post, bear with me.

I just recently finished restoring a 1967 Cadillac Coupe DeVille 2 door. I put a chevy 454 in it. It makes 557 HP at 3715 RPM and 607 Torque at 3265 RPM. I have a beefed up Turbo 300 in it with the factory rear end. It has modified Corvette suspension on both ends (came out a C4) with heavy duty shocks and Coilovers. It also has 285/50/18 front tires and 325/45/18 rear tires. My question is: what would be a good automatic to run? I want to put in a 3.42 or something of the sorts. It is mainly a highway cruiser but it is at shows alot. It spins up a decent RPM right now and I dont like it, I drive on the peak of torque basically. Could you guys help me out? Thanks! -Paul

 

While I am at it, here is my list of mods:

High compression pistons (bored .030 over)
Different head with bigger chamber and valves
H.P. Street cam
Holley ignition system
Edelbrock dual plane intake / twin 600 carbs
high flow fuel system
Upgraded power steering pump
High charge alternator
Tuned length long tube headers
2 3/4" dual exhaust (X pipe)
twin cherry bomb vortex mufflers

 

The owner of the vette had pit a 4.11 in it so it would get speed and go, I never bothered to change it out.

 

I might go down to a regular intake and use 1 of the carbs.
