I want this to be a 400-500 hp engine after headers, cam, crank, and anyother mods I put on it, I dont want to put a LS series engine in it I want this car to have an older engine not something new1975 Trans am 455 8.99 @158mph (What now fallguy)

No freaking way not if you're trying to get 400-500 ponies.
The 455 is a pretty potent motor but to get that kind of power you will need some aftermarket heads, intake, headers, cam, and a pretty good carb setup and big block parts are never cheap. I know on the BB ford heads you can machine them out and put bigger valves in to get the flow you need to feed that kind of power but i dont know on the 455. Edelbrock performer RPM's will run you over $800 a piece. I know for a fact that you can get the whole top end kit from edelbrock for a 350 for like $1500 and thats good to about 450 with cam and headers. If you build a stroker like a 383 you can easily push it over 500 hp, but it aint gonna be cheap to get that much out of a small block, or any engine for that matter you have to build it to handle the abuse. You gotta remeber none of these engines were ever meant to push that much power if you cross the line you can get bit in the ass pretty easily. My advise is talk to some guys who have built a couple of 455's the net is a great place for that and do your homework.

A regular sbc is pretty cheap, but LSX engines are considerably more expensive. This place has some good options:

Anybody in here who reccomends a chebby motor be put in that PONTIAC Trans Am should be slapped.
The 455 is a beast. It makes a helluva lot of torque and lots of power but you don't need to spin it up much. A 400 punched out and stroked to 462 is also a helluva combo. Bottom line is stick with the pontiac motor in that car. Its a lot easier than dicking around with putting a chevy in there (motor mounts, accessories, fitting under the shaker scoop and various other things).

I agree with cmk i just had to comment on the big block cheaper than a small block bullshit, what was that guy thinking? Anywho the power of the big block compels you. The power of the big block compels you.

That really depends on what deals you can get.$400 for a 455 and a 400 is a damn good deal.

I know a kid from back home with a built 455 olds in a old jacked up chevy. I havent heard him having any problems with it and he drives it everyday, it seems pretty reliable. Only thing that ever broke was one of his axles.That's an Olds 455 in place of a 5.7 deisel slapnuts.

Also, the LS1 and LS2 were installed in the Formula/Trans Am and GTO, respectively, so putting them in a Pontiac would seem reasonable.

The LSx does not bolt right up to a 2nd gen Firebird. Also, they were only in the 4th gen 1998-2002 models. The LSx was never installed into a 2nd gen bird.
The Pontiac motor will be the cheapest route in that car.
BTW, there is no "big block" or "small block" with the pontiac motors. They are all the same physical size.

The general rule of thumb for those of us in the know is that big block parts will be double the cost almost all the time.
