I bought a 55' Chevy without a drive-train recently. While looking for a big block in Craigslist I came across a 454 about 1/2 hour from my home. The seller installed a diesel in his freshwater boat, and wanted to sell his 454 for $1,700. He said it would work fine in a car. He said it has 330 Horsepower and the cranking pressure was 180 lbs. in each cylinder (180 Sounds high). I'm figuring that the exhaust manifolds, water pump, Carb, Camshaft and distributor would need replacing. I want torque for the street, not horsepower and thought this may be a good deal. Would the back of the crankshaft need to be modified to work with a TH350 or 400? I'm told the water passages are different, also no heater hose attachment . Any "Boat people" out there (No wetbacks)?
