Hello I’m new here and need alittle help, I got a 1989 Larson 20 inboard with 4.3 mercruiser, so the motor is seized up I tried soaking the cylinders and didn’t free up, so now I was thinking off taking all the marine stuff from the block that I have now and pull a 4.3 from a car and swap all the marine stuff on it, I’m not sure if you can do that, I have a few friends saying you can then I have a few saying some of the 4.3 blocks are alittle different, by the way I am a mechanic so I’m alittle knowledgeable about this stuff so I know all 4.3 are the same that I know of. I’m just wondering if I can pull a car engine and swap some stuff over to make it work? Is it possible?
thank you. My name is Tyler
