found a nice 99 C5 LT1 with a rod knock. I see replacement motors are a lot more than later LS junk yard motors. Any suggestions for an economical replacement? Camaro engine?

Yes Camaro or Trans Am LS1 should work just fine.

Maybe the LS1 could be fixed?

You could even use a 4.8, 5.3, or 6.0 gen 3 vortec pickup or van engine, however the iron block is heavier than the aluminum block of LS1, of those engines, I would only use a 6.0 because of the increased power potential.

Did you buy this car already?
