I'm Awesome
Decided to post pone the Proflow intake and put the L31 Marine intake back on the van. This manifold was worth 20-30 hp between 5,200 and 6,000 rpm on the 350 when it cammed compared to a ported truck manifold. Will be interesting to see how the 383 responds to it. This is a place marker for more pictures I take detailing the swap. Much of the older swap information is gone. I want to also provide infomation on swapping the harness to the matching Deatschwerks connetor so that an inexpensive AEM harness connects right up to the OEM harness like it was built that way. Both my OEM spider connector and marine intake have the Deatschwerks connectors on them. While I have it apart, I will show anyone that wants to know how to install that connector. Basically one cuts the OEM injector wiring after the 1st splice so that there are 4 remaining injector power feed wires on each side of the OEM injector connection wiring and grafting a plug on to it. Makes the intakes easily swapped with no wiring changes. I am leaving it that way in the event that someday I may have to put the OE intake back on for whatever reason. I did some port cleanup on the marine manifold, cleaned it up and re-painted it. Its going on tomorrow.
