Also, if the 5.3l is the same year as my truck, will there need to be changes on the 5.3 wiring harness prior to the install?

Thanks

Carnell

p.s. What do you do at NAS Pensacola?
it's a camshaft - 212/218 are the intake/exhaust valve lift specs, which are what cams are generally referred to by
for the harness, so long as both you & the donor use the same transmission, you shouldn't have to change anything that i know of

you can do the DBC swap on a newer motor, but i don't remember what all's involved. search around & you'll come across where people've done it before
