I started this tread really seeking input on mentioned cam to see if there was merit in the cam design. I do have some interest in the XFI lobe since they are designed for EFI like I plan on using. I would love to find the tread that Wyrmrider was talking talking about. That said, I may be over thinking this. I talked to a couple of friends yesterday. One has a '69 Dart with the mild 340 that he drives daily during the summer, and the other just finished a '63-64 Chevy pickup with a 5.7 first gen LS. Our discussion centered on the fact that neither have as much horsepower as what I should have, but they both are just fun to drive. In the end that is what I am after. Thanks everyone for the input and suggestions, it's been helpful. Keep it coming if you have something more to add.
