You mean 5.3 truck motor to a 5.7 LS1 right?

Yes it will.

I have to assume that you're talking about a drive by cable TB. You will have to swap the throttle cam from your 01 in order to make it work because the truck on is small like the 98-00 TBs.

The older truck TBs are the same as a 98-00 f-body TB with the exception of the PCV port uses a longer tube on the truck one (which wouldn't matter). I have one of each right in front me. Since most trucks switched over to the DBW TB in 2000, I've never seen a newer style DBC truck TB. So it may be the same as the 01+ fbody TB as well.
