Yes I mean a real Pontiac V8.

Long and short of it. I was thinking of putting a Pontiac 400 in my 84. Mate it to an LT1 T56. Run the factory 10 bolt 3.73 rear. (I know the rear might not hold up, that is not the issue here. I'm gonna upgrade the rear last when it blows up.) Power figures will be in the 475 HP range. Hoping for a redline above 6,000.

Issues:

1. Can you keep a factory 84 TA hood? I want this thing to look bone stock to people who don't know better.

2. Can a Pontiac motor of any kind be mated up to a LT1 T56? If so, what does one need to accomplish this? I think it can be done but I don't know the specifics.

3. What engine mounts will work? I've heard of certain factory mounts working without raising the engine so you don't have to change the hood.

4. I saw something about stroking a 301 Pontiac motor into a 383? How the hell is that possible? It doesn't seem to be. My dad liked the 301 in his 77. Said it was a nice high winding motor with plenty of torque. He had a 4 speed in that car. I was wondering if the same characteristics will carry over to the stroked motor if such a build is even possible.

My other options are of the SBC variant. The 383 or the less common 406. Either will easily rev above 6K and produce the power I want. The 383 is the easiest and cheapest route. The 406 will probably require a $$$ swap flywheel to work with the T56. But there is something about a Pontiac motor in a Pontiac, that seems to be alluring. I've posted the same questions on TGO. But it would be smart to take advantage of the local boards for local resources too. Thanks guys.
