Single throttle body EFI intake

looks good, similar to what I was thinking.
My plan is to keep my eyes open for a cheap tunnel ram lower unit without the top carb box portion, cut and machine it to accept my own fabbed up plenum box with TB flange and add injector bungs.

Good luck, been looking for one for a while now that is under $200. No dice. The "power elbow" bolt on 90 is a great option too, you'll lose the 'wow factor' but it works. I think my sheet metal intake project was under $40 in metal store scrap bin minus the Jeep TP and Magnum fuel rails. Both were almost "buy it before I toss it" shipping only buys in the classifieds here. My next one is going to have round runners as its easier to hole saw rounds than cut square windows!
