Information.. Alpha I/gen2. I just replaced my 4.3 liter V6 with a 5.0 liter high performance V8 (I said 5.7 because you don't usually get this much out of a 5.0 and the 4.3 is 225hp). Amazing how little you have to change! Almost everything is a direct swap to the V8. I had to buy exhaust manifolds and the rear aluminum V8 elbows (both ebay..). Had to move the motor mounts forward. The Thunderbolt IV distributor needed a V8 rotor and cap. A little work on the hoses (had to extend 2 of them). That's it. The water pump, power steering, alternater, starter, etc. all bolted right up. The motor slipped right in and runs great. The outdrive gear ratio is a little higher than for a normal V8 but it's fine (1.64:1 as opposed to 1.5:1). Just thought someone may be interested.
