5.3 to 6.2 intake swap

[durandetto]

So I'm getting ready to order kooks long tubes, off road y-pipe, potentially a cai and the 6.2 intake and t/b. I work at a repair facility and get a deal on dealer parts. Is it worth the extra $200 for the ported t/b? Also 1 7/8 or 3/4 long tubes on a n/a engine. Cost isn't much different, but I don't want to have any adverse effects going too big.

What’s the goal? What’s the main purpose of the truck? Hi ram will move your powerband wayyyyy up. You’ll lose your low end TQ. You’ll need to run a looser stall with the hi ram.

Highly considering the same setup as you described. How did this turn out for you?
