I have a 93 Wellcraft Excel 20SL with a 430B engine and a SP C out drive. I threw a conrod and have access to a 2000 4.3L engine that has throttle body injection. I would like to know if it will fit, what changes would have to be done, if anyone has ever done this, etc...

The flywheel might not fit.You need to compare the crank ends.
The fuel system will also need to be changed over to a marine system or use the old.If it fits?
Get a V-6 block closer to the year you have.
Someone just asked this question a short time ago.
Use the search system.
