Need help on throttle body

[bootlife]

I have an 05 LS2 corvette intake, going on a 2000 6.0 that will have a 226 cam. The intake is 90mm I think factory, should I run an 85mm or 102mm throttle body?

[farmtruc]

Run the larger one. At least a 90mm

K thanks

I have a 90mm I'm selling

[bootlife]

I got the 102mm, came in couple days ago, what all do I need to do to put an 05 vette intake on a 6.0 n an 04 Silverado? I have the intake, TB, already. I'm doing this on a budget so keep that n mind,

I'd double check but you might run into clearance issues with the neck of the water pump.

gonna need a car style water pump, spacers for water pump, relocate idler pulley to center bolt hole of alt/ps bracket and a different size belt

[bootlife]

so like what year and make car water pump, or does it matter long as its a 6.0? Where do i get the spacers from?

also, The Motor is out of a 2000 HD, so with that said, Im doing LTs, vette intake, 102mm TB, cold air, 228 cam, built 4L60E trans, 2800 stall, 4.10 gears Nelson Tune. What else should I do, and what do yall think it should run 1/4 and HP wise?_________Im Thinking bout going ahead and do some flat tops, and trash the iron heads and run a set of 5.7 GTOs.

Definately Trash the iron heads. Also, not sure what vehicle this is going in, it migh be more cost effective to go with a 90mm truck intake. Less crap you'd have to deal with changing around. If you go with flat top pistons I'd estimate around 375-400 from your combo. Also, the truck intake would flow more in the lower rpm range which would give you more low end torque.
Your setup seems similar to mine and I ran a 13.1 @99. I'm running an iron ls1 with milled 241's for heads. What springs are you going with for the heads? I'm assuming you know that the stock springs won't hold up.
