[Gmecm] engine convresion

[trekfan]

I?ve been reading this list for some time now, so here goes.
The vehicle I own is a 1992 Lumina APV(van) with the 3.1L Vin ?D? engine and
the 3T40 automatic transaxle. The intake is TBI speed density it also has a
distributor. The only trans control I see is for the TCC. What I would like
to know is does anyone know of a multi-port MAF conversion or any ideas on
what parts (intake head, ECM
etc) to build one from scratch. Thanks for any
help at all
