Is a 454 into a T/A possible?

[93CivicSiD16HB]

I was just wondering if there was a way to fit a 454 into a 98-02 Trans Am, like if anyones seen it done, because i'm looking at a T/A with high miles and was going to just swap in a new remanufactured 454 from GMGoodwrench, and just hoped maybe there was a engine mount kit or ANYTHING of the sort or related info. I know i'm going to need quite a few parts but money isnt the problem here, just wanting to know.

Thanks!

Heres the Engine

The 454 HO offers tremendous value in a big block crate engine. Based on the Gen VI block, this 425 horsepower cast iron head engine is a great choice for that muscle car in the garage. We've heard of several of our customers replacing their rare matching number 396, 427 or 454 with our 454 HO in order to drive their car on today's gasoline without fear of destroying their classic engine.The HO stands for high output, it also stands for big valves, rectangular ports, forged pistons, forged steel crankshaft, forged connecting rods and four bolt mains. Sounds a lot like the performance big blocks of the late 60's doesn't it? When you add in the steel roller camshaft, shotpeened rods, windage tray, one piece rear main seal and high speed single roller timing chain, it starts to sound more like the performance big block of the new millenium. And it is. The 454 HO makes 500 ft.lbs of torque with its rectangular port open chamber cylinder heads. With 118cc combustion chambers, the modest 8.75 to 1 compression ratio loves today's pump premium and has no appetite for lead, octane boosters or other fuel additives. Its 2.19" intake and 1.88" exhaust valves and high lift .510"/.540" roller cam let it breathe with the best of the early muscle motors. With your carburetor, HEI distributor, exhaust system you've got a muscle cruiser worthy of your time, effort and expertise. And, if you want to use your muscle car's fuel system with a mechanical fuel pump, you can because the 454 HO Gen VI block has a conventional style fuel pump boss.

Not worth it.
Yes, it can be done, but it is VERY costly.

There is a warlock block being made that can support up to a 500 cubic inch LSx.


Just 425 HP eh?? My little smallblock 402 LSx makes 600 at the crank.
Stick with the LSx series for a 4th gen.

Agreed...especially if money isnt an issue. I would just pull that LS1 and make a killer motor out of it. It will still probably be less expensive go that route and youll make more power.

I agree with Luos and Creeping. Nowadays you don't have to use big blocks to get hp. Like Luos said, go with the small block and you can get more power/torque for less and it will be more reliable, and you can also keep the fuel injection. It's the same thing with Mustangs. Some guys ask about dropping in a 429 into a 87 and up Stang. WHY??? All it does is add more weight. If you want more c.i. just have your stock engine bored and stroked or get a bigger small block from GM performance.

Yeah, it would be cool to see an old/new big block under the hood of a newer T/A or Stang but, unless it's a complete beater, I can't see going threw all that trouble. GOOD LUCK

The biggest selling point is to able to claim you have a 454. The money would not be worth the return. Given the amazing power figures and abundance of performance parts for LS series go that routs, and take the money you would have spent adapting and spend it on the right combination of parts
