Gen IV thorttle body sizes
What are the sizes of the Gen IV engines TB's. Been getting conflicting data.
4.8/5.3 87mm??
6.0 L76 (truck) 87mm??
6.0 LY6 87mm??
6.2 L92 90mm??
Looking at L92 heads and a truck intake. Would like a 90 mm DBW TB. I though the L92/L76 were 90mm?

I am curious as well. I know this doesn't help much, but the LS9 runs an 87mm throttle body, and it looks like a truck style unit with the compact motor on the side, as opposed to having the motor stick way out like the LS1 and LS2 (and possible other?) Corvettes.

Thats what I am looking for if they are all 87mm?
I was thinking a 5.3L one if it was 87mm night work well on an eariler motor vs get a TBSS intake. I have heard of them being ported and running a 90mm on them.
