My old Vortec head TBI when I still ran it. Had an Edelbrock Performer RPM and 502 Marine TBI on it in this picture but later ran an edelbrock 2912 single plane.



I played with TPI on a 383 as well. Stock runners in this picture but I also ran siamese ported SLPs on it.


I also ran Doug Thorley TH-315Y headers on it from with every engine from the stock 305 through the 383.
