1973 Dart 340 Sport Project

Finally fired up the engine! Nothing like that to get your interest in the project back up where it needs to be. Started up right away, ran it for 30 minutes at 2500 - 3000 RPMs per the Comp Cam break in instructions. Sounded really good. Had a short video but can't figure out how to post it. The Dakota Digital fan controller worked flawlessly, temp got to a max of 205. Fans cycled on and off just as programmed.
After the break in I went to my machine shop guy, George at CAMS Racing Engines here in Gloucester. Planned on getting some more Brad Penn break in oil and the Comp Cams additive and doing an oil change. Probably get varying comments on this part. George suggested no oil change yet. He asked how long it would be before I drove the car, I told him 4-6 months. He said before I change the oil, I should get the car up on jack stands several times and run it, going through the gears, to get some load on the engine. I've always heard to change the oil after the initial break in but he says the break in will be more successful with a load on the engine after the initial start up. He builds many late model engines, hot street engines, plus every Monster Truck engine so he knows his stuff. I'll follow his instructions.
