Is or was the motor balanced? If so, internal or external? M
I need to do the opposite. Flexplate to a flywheel. External balanced.

Aaaah yes I can see a few good looking shiny tall deck motors on the beach, with barely enough fuel to get back to the launch saying, "Holy crap how fast you think that Daytona was going man? That's like the 20th time he's gone by today?"
Sooooooo.................. Yes or no..... changing the flywheel to a flexplate won't affect the engine.
Its ext balance.
This is my problem, I originally set up the boat with a BBC 454 with a flexplate... Now i bought Beerjets engine and it came with a flywheel.
Now the engine needs to be moved forward about a 1/2" to make up the diff and need to buy longer bolts to install, PTO and flywheel..
Or i just buy another flexplate and put everything together
I just want to make sure im not going to hurt this engine
Take the balance card and the old flywheel with the new flex plate or vise versa to a decent machine shop that does balancing and if he knows what he is doing should be able to figure it out. External balance is putting everything in-balance on the ends of the crank that is not in-balance inside the motor. Factory uses a scale of in balance and not. That would be why you have weights on the balancer and the flywheel/flexplate. A good balancer will get balance within 1/4 gram, inside or out. I would try to get as close to the balance card as possible.
