Agree 100% Send it To Precision Marine!!!
Save your self some headaches. Build a crate and send your motor complete, along with YOUR exhaust and send it to Mark at Precision in New Orleans. When you get it back, it will be done right, drop it in and go.
Many many happy customers.

I machined about an inch off of the lower intake to eliminate the restriction of airflow under boosted conditions. The long runners are for N/A torque. No need for that with a blower. To save time, I used a carbide tipped router bit to do the radiused edges ( cuts right thru the aluminum) and then finished them by hand. Doing this and a small cam spec change, got me 50 more HP and 200 rpm up top.

My boat ran good with the stock 502's and the prochargers. Im making some changes and i want to dump the fmu. Mark at precision informed that with mefi 1 i cannot run the 2 bar map so i must either keep a fmu, change mefi ecu's, aftermarket efi or carbs. My first choice would be the dominator efi but its not in the budget. Not sure what to do.
