Merc 454 TPI work on 496 with no issues?
I just picked up a 1997 Baja 272 Islander with a 496 crate motor installed with a carb instead of the 454 TPI that was pulled out due to a cracked block. I asked why he went with the carb and he is simply an old school hot rodder that hates messing with fuel injection.
I would much prefer the fuel injection and I did receive all of the parts along with the old motor in the sale, so are there any reasons/complications to prevent me from putting the FI back on?
Thanks in advance!

What intake and carb was used on the 496? Does the old FI setup look like this?

It came off of ebay. Here's a link to what the motor most likely is. I'm still waiting for the paperwork from the previous owner.

Got it, thanks. I'll just throw a bigger carb on there until I build up another motor then.
The previous owner bought the boat at an auction and found water in the oil and a freeze plug pushed out. Just for fun does anyone care to hazard a guess as to whether the crack is indeed cracked, or that it simply pushed water past a seal? It's a MarkVI 4bolt main block.
