Hello everyone
I have a 1981 commercial chassis (hearse) 368 45,000 miles w/ turbo 400 trans
only upgrades is quadrajet carb, new fuel pump and emissions deleted.
I have installed this engine in a 1953 Chevy 210 (2600lbs) and 3.73 gears and have logged several hundred miles on it.
Now I'm looking for upgrades

Cam, lifters, Intake, flat or dome pistons, headers
My goal is 450hp and 450ft torque street motor with a noticeable idle.

what do you advise to reach this goal?
What works ( part swaps between platforms ) ect. ect.

Thank you in advance for your suggestions

Godspeed
MrC.

No its a frame up build, I put a mustang II under it and a 10 bolt rear with s-10 leaf springs.
It has 4 corner air suspension so there is very little roll.
Future plans are to 3 link the rear.

The engine/trans was free to me so I used it. I did call Cad company, the only options for this engine is a cam/lifters and springs. total hp gain would be about 65hp.
I have a ad out now and I am searching for a 500/472 since it will bolt right in, I like the "how'ed you get that in there" and "what the heck is it" aspect when I pop the hood.
So I will just drive it as is until I can find a 500.

Thanks for you
Input.
