Truck manifold intake swap
All props to dustin lacy
Ok guys. Here's my write up on the TRUCK MANI Swap:
First of course you will need a manifold from similar years as our cars. Newer can work as well but may have the same clearance issue as the TBSS intake. Which I don't recommend unless you want to do extensive work to the intake or relocate the power steering reservoir. There is a link in comments on the shaving of intake. This process is tedious. I found JB weld to work better for smoothing than Bondo. You can use the truck rails but must be NON-Return style. Or can use holly EFI fuel rails or equivalent. I used stock injectors w/30mm top hats to make fit. I recommend the 11mmx24mm for closer fitment. I opened engine wire harness to extend/loosen some wiring due to height/tightness of new intake. I also soldered wire extensions on MAP sensor wire to relocate to rear of intake for clean look. Stock MAP. I installed one 3/8's fitting cut from intake/relocated to rear for catch can and fuel vapor line attached to stock TB. ⬅️Also relocated to fire wall. I used a plastic 1/2"barbed fitting for brake booster. Mounted as close to stock position as possible to reuse stock hose. A 3-4 bolt LS TB adapter will be needed. I used an LS2. But 3/7 can be used and even an 87mm 4 bolt truck TB can be used. Stock can be used but finding plates are difficult. Also the alternator bracket must be shaved a great deal. That's the jist of it. Not for the ones who can't fabricate or problem solve. But not impossible. I know I had help. They know who they are. I'll include as many photos as I can. Have fun and mod on!
