I would do this :

Ebay the crank , rods , pistons , etc....separately. get what you can .



stop messing around and call 440 Source and get a 4.15 kit and be DONE .

Have Jim or Steve or a machine shop check the kit.

Then grind a tiny bit off your oil pickup boss and bores for clearance.

DONE.



Come on Ted...I know you've been working 60 hours a week........BUST OUT THAT CREDIT CARD !!!
