1954 Cadillac 472
I have a 54 Series 62. It has a 1970 472. I converted it to EFI using the 1975/1976 Cad Hardware and a Megasquirt II V3 computer. It also has a Cad V8-6-4 computer controlled distributor. It has homemade headers with Flowmaster 70s. I made a homemade ram air setup. Currently it has a turbo 400 with a Hurst shift kit and a Hurst Auto/Stick 1. I have been building this car for over 20 years designing and redesigning it to make it better. I have been restoring/restomoding an original AC unit to work with the 1970 compressor. I'd like to put a manual in the car.at some point. So, I have been doing research for the mod. Attached are pictures.

That is cool and tastefully done! First year of the GM A/C.

Why are you considering a manual? You already have a floor shifter, you could change your 400 valve body to a full manual shift easily enough. Is it for better gearing?

I would like to lower the revs at cruising speed. Also, I am looking to upgrade the cool factor. When I started building the car I wanted to make a phantom Hurst Cadillac. I thought if I could get a 4 speed into the car it would be ultra cool for another unique feature for this car. I know that 4th gear on the 4 speeds is direct, so no overdrive or lower revs. But, I have not done anything yet. I am in the planning stages and I am researching everything to make it happen if I decide to do so.

I don't know if putting a stick in that is such a good idea:eek:. One higher RPM side step and things will break:cry:. Weight of the car, torque of engine, and if stock rear. Disaster will strike! Yeah, I know:rolleyes: "You won't THAT";). Yeah, right:whistle:. Nice sled:cool:.

I'm not in the camp of standard transmissions.

I am in the camp of seeing you do it if it suits you. Besides, who ever put a big Caddy engine in something thinking that nothing was going to break?

That 6 speed idea would be cool for sure.
