502 MPI build help
 

Hello,

Building up two 2000 year MPI 502's. The engines mechanically are completely rebuilt and solid, block, ring, heads, etc. So not I need to put the accessories/electrical on and have found they have corrosion/salt water damage on many parts;

Electrical Harnesses
Power steering pump
water pumps
alternators Mando
MPI sensors (all)
Cool fuel
Alternator bracket (1)

After seeing Mercruiser prices I was sticker shocked. I would love (only way affordable) to find good used MPI parts. Can anyone point me in the right direction for used parts, a parts motor, ideas, etc.

Thanks, I want to get this in the water ASAP.

Check with some custom engine builders like Teague, Crockett etc. They sometimes have FI components taken off a new engine someone brought to them to add a blower etc.
