I know its been covered a thousand times but seems like most people don't do stock, carb'd engines. I switched from stock EFI to Victor Jr./QFT750/MSD6010 and am wondering if the TR55's I was running while EFI are the best for my newly carb'd stock 5.3. Engine was pulled out of 2004 Tahoe, cleaned up and dropped into my Monte Carlo, so when I say stock I mean 100% stock.

They will be fine. That's what I did on first fire up and also a few passes.
