New elevation of the motor puts the truck manifold just a little higher than last test fitment. I read the TBSS intake is slightly shorter but I cant find any real measurements to confirm. I priced out a Dorman 915-601 and its $1750 CDN my cost ?!?! The 915-600 is no longer available as its super-ceded by the 601. Guess thats off the table lol. Hopefully I can find a used LS1 intake locally or something half decent alternatively that fits.
