400 sbc upgrade. Efi options.
Hey everyone I'm currently building a new engine for my 1986 Chaparral Villain III. It currently has a carbed 305 in front of a cobra 1 outdrive but all that is going away. I'm building a 406 sbc, 64 cc vortec heads, flat top pistons, steel crank, 3.75 stroke. Hydraulic roller Cam, lifters and rockers. 249-SK12-418-8 is the Cam. Fresh water cooled. Bravo 3, 2.0 ratio currently. But I also have a 1.5 and 1.8 bravo 1 lower I may use. 26p prop. My problem is fueling. I have a stock Mercury marine mpi system off of a 350ci and would like to use it but I'm not finding many tuning options for it. I don't have want to use a carb as the engine will be on and off a ton for towing. Does anyone have any experience with tuning mpi or is there another aftermarket efi system? Thanks.

Awesome, thank you so much. I'll get pictures and part numbers for the mpi I have. I was kinda planning to use the b1 stuff but figured I would try out the b3 stuff since its already together. I plan on turning it around 5500-6000 wide open. Do you know where I could get the tuning software? Or would I have to take it to someone.
