Default F.A.S.T. 90mm Intake Swap Progress

Here is a few pics of the conversion so far. Still working on the brackets for the truck injectors. Should have gone with the 97' vette fuel rail & f-body injectors/pigtails

Here is the ported 90mm F.A.S.T intake from Vengence Racing. I got the throttle body from them as well. Can't remember what brand the tb was, but it is a nice piece of billet aluminum.







I also installed a LS6 valley cover. Had to cut a chunk of metal out of the valley on my 98' LS1 block to make it fit.



Here is the difference in the height of the FAST valley cover bolts (left) & the LS6 valley cover bolts (right).



Here is a pic of the LS6 valley cover, L92 water pump & Speartech Idler relocation bracket.



I'll keep posting pics as I get more done!

not tryin to be an *** but the ls1 style injectors would be the best route..the truck injectors are at a different angle also..steel braided fuel lines and the new blue scorpion aluminum fuel rails would be badass on that..
