Some people just shouldn't own a mopar

You didn't want to be around my place when I built roller motors in the 80's. Fire it up, set timing and carb(s). Make sure the cooling system was working, good oil pressure, no leaks.

Spray down street, 6500-7500 rpm burn out. All broken in... Some of the SB 283-302 Chevies were turning 9500... lol

Outside of running them to get temp in them on a dyno, while doing that you put some load on them and release it. Puts pressure on rings, etc. After that, rip away on the dyno. Short runs to mid range RPM verifying carb jetting, looks good, rip it to upper ranges.

I remember those days , Build-em Race-em blow-em and rebuild-em. We have racers come here that melt them down on the dyno . Those days are over for me . Just can't afford the parts prices today on my retirement. As you get older you start appreciating these old Mopar engines and how hard they are to find.
