540 MPI Can I do this?

[sledge]

Didn't Lingenfelter design the MPI/EFI intake?

Lingefelter design that intake for merc back around 1992-1993,he use to also make a 540 kit that was a modified intake,ported,shorten runners,camshaft,and re-program ecm,he was one of the few that could reprogram the mefi back then.A lot of those intakes were removed back then and were replaced with a good carb and intake for more easy power,modified those old 502 mpi were i guess just ok not great,the stock hp500-525 intake probably still flows better,anyone ever tested one against the other?Also the mefi 3-4 do a better job controlling the injectors then the old 1-2 mefi,seem to burn cleaner and easier to keep a good tune

Thanks for the offer Jay, but I am really looking to build my short blocks and maybe do a little dyno time and be good to go, those look sweet though.
