Spent some time in the search function and couldn't find a definitive answer on a couple of potential issues. I injured my 454 engine (Jet), it's out of commission for a few months. Located a 427 TD for cheap, thinking about popping it in if I can get it to work without too much trouble. It's sitting in a farm vehicle and starts up so easy and sounds very good, not even a hint of exhaust smoke.
My first question is this: Will this stock 427 get my heavy jet on plane? I was turning the 454 @4,200 rpm. I don't have a clue what kind of rpm to expect with a torque monster, low hp piece.
The 427 has a flywheel (454 has flex plate): What's the work around? Can I put a flex plate on this 427 and keep the engine balanced properly? Does internal/external balance factor into the equation? It's my understanding that the tall decks are internally balanced? If I'm forced to keep the flywheel, will I'll need a shorter u-joint or PTO adapter?
Damn, the factory intake manifold is problematic on the 427 in that it has the double thermostat deal and some other funky crap. Any way to side step that housing and go with a traditional 454 water divider/housing?
Since the block is +.400, will it be trouble connecting my exhaust tubing without relocating exhaust tips?
I'm not crazy about this idea and to be honest, I'm ok with sitting out the summer. However, I feel obligated to my kids to get them back out there if can be done relatively easy.
I have no intentions of using the Tall Deck once my 454 is ready, that's why I don't want to waste time swapping out the intake, getting spacers, slip collar distributor, etc, etc. I can get the 427 cheap enough to break even parting it out so I'd rather not molest it too bad.
Seller priced it thinking is was a 366 and even after helping him determine is was a 427 TD he agreed to sell it low.
