I thinking new engine for my c4...
What is the best choise of junkyards engines. I watching 5.3 and 6.0 engines, with low miles. Those engines are very cheap with ecm and harness.
My c4 is streetcar with zf6, dana44 and I have procharger D1SC for this setup. I thinking 700-800rwhp would be nice...

I want stay in stock engine, checking and stronger rods bolts.
To change camshaft is too possible, but idea is so originally that possible.

Could you tell me, what is the best option 5.3 or 6.0 and which is engines typecode ( example LQ9)

I found lot of story of 5.3. Is it better than 6.0 or is that popular for low price...
