Default ls3 GMPP Crate motor first start
i am considering a first start without coolant and exhaust. Goal avoid a bloody mess if something happens be able to ck for fuel leaks Back in the day of flat tappets this was never an option as you had to break in the cam. Also I cant run it long at all due to noise..

Curious if this is a bad idea.?

Alternative bring it to exhaust shop on trailer having e=never been run bring it home fill it with fuel and water and start..
