Looking at swap numbers, I think I would rather do a little extra work and swap in a 3500 or build a hybrid 3400/3500. Here is a list I have found at V6Z24.com and im pretty sure that the J body and L bodies are very similar.
LIST:
-3.5 L v6 engine (LX9, non VVT)
-Fuel Pump from a 1991 TPI 350 Camaro
-3100/3400 fuel rail
-88 Beretta GT Jackshaft setup
-#24 injectors from a 3.4 DOHC which are Multech 1 or Multech 2 from a stock 3400?
-Snap-on flare set of fuel lines from a 3x00 equipped vehicle (grand am possibly)
-External crank trigger from

-Front mount
-Side mount
-3500 plenum TB adapter from

-65 mm 3.5L intrigue Throttle Body or 65 mm TB from TCE
-Manual Transmission from HM282 Getrag/Muncie
-Aftermarket clutch and pressure plate, im going with clutchnet.com
-New Flywheel, make sure to use manual transmission bolts
-95 Beretta/Corsica Throttle Cable: GM P/N 22638838

-Power steering line from a '94 Grand AM with a 3100
-Downpipe from 3500 engine
-Set of steel "union" pipe connections (3/8ths for the supply line, and 5/16ths size for the return line)
-CTS adaptor: carquest, PN# G63120-1206 12mm-6FP
Now that i am working, I will have the disposable income needed to do what GM forgot to do......use a motor with more than 130hp. I was wondering if there is someone who can tune the 3500 with multec 2 injectors.
