429/460 swap

[oldman]

I put a 351-C in an 82 GT with good success and it's real close to the size you are talking about. The one big thing is the steering shaft. No matter if you use the swap headers or not, the stock steering shaft flange will hit the exhaust (hard enough that you won't be able to get the engine in) unless you re-engineer the thing. Flaming River makes one for about $130 that will work. THe c-6 fits well, it fills the tunnel but it goes in easy and there's plenty of room to manuever afterward. Naturally the springs will look like they had an elephant sittin on them so you'll need to go heavier on the front at least. I know this doesn't exactly addressd the 460 install but like I said, the physical size is so close it won't be much different. Good luck
