Yea, I know - this is an old thread. The big trouble I see with using these 5.3 liter truck motors in a car is the 5.3 liter oil pan. It hangs down a lot.Typically, maybe two inches or so. Yes, the 5.3 liter engines are abundant and cheap but you do need to budget for a different oil pan. Otherwise, you are going to leave your engine oil on the street someday and quickly weld up the internal parts of your engine into a pasty grey metallic pulp.
I had to go with the Holley 302-2 pan on my El Camino to avoid this problem.

4.8 compression height Edelbrock duel plane and 670 Holley. It runs like a raped ape.only downside is you need at least good 93 octane.unless you pull timing and works fine.
