Engines look great. Question I have is why would he have an outsider do the programing? When I built a 500EFI it was programed at the dyno shop and tweaked while on the dyno. When he was done I was told that after installed in the boat and run, if I wanted, to bring the boat and he would check the tune on the water with a laptop.

Thanks Jake. He had the computers reprogramed for 540 cubic inch motors. Now he will tweak them at the dyno as well. Mine are or were two completely different animals. Nothing even close about the 415s mine were before. Calibration got the computers in the ball park so to speak and now he will tune them. Hope that makes sense of what I'm trying to say. My new motors started out to be 509s and 500 HP. That's what I started the thread on. After Ron got into them and bored the first time he called me ask If I mind if he just bored to 540s and put stroker kits in them. I told him absolutely not I didn't mind. So now we should be right around 617 pounds of torque and about 600 HP. No longer just 500s. Is that what's throwing you off on why he sent the computers out ??

The work these guys do is almost insane. They didn't reuse one nut or bolt from the old motors. I stopped by Saturday to pick some of my old parts and there two card board boxes toped off with nuts bolts and washers. I ask Ron were did these come from? Are these mine? He said yes they are yours. Only thing they kept and reused were the brass fittings and those were hit with a wire wheel to clean them up. Look threw all of the pictures from the beginning on the thread and you will see what I'm talking about. I have never worked with anyone who is such a perfectionist as the guys at Potter. I certainly got my moneys worth.

Those intakes can support 600hp? wow

Thanks for the info Lucky. Hope you achieve your goal..
