I am going up to Canada, sorry. But don't worry, you've got more air and more fuel than I have. My pump is stock and I have smaller twins. You were 420 on number 2 before twins and head. I was at 370 before twins and 462 after. You are probably at 480 to 500 minimum. Piers is changing my injector lines and trying to fix my idle. I doubt that my truck is going to sprout another 40 or 50 hp from that. Don't get me wrong, I'd love it. But this p-pump conversion is nothing like an electronic pump. Cam, head, twins and a chip would be at least 550 on one of those. It's 462 on this. Still way better than the 195 hp motor i took out. Besides, I figure i owe you something for sending that stuff up that didn't work.
