Roller Cammed 318/360

66dartgt: Good for you man! As hot rodders, we are really scientists transforming theorem into fact, with the dragstrip, garage and the seat of our pants as the lab. Crane as well as Comp will make any cam for us, as long as we have a a few extra bucks mixed in with the lint (as Rumble so aptly put it!). The last engine I built (the one in my avatar) for my Ramcharger is an experiment and I probably have more time in the heads and valve train than the rest of the engine. Custom pushrods, custom rockershaft spacers (no spring spacers for me!), lifter preload on the button at .040, and the closest to vertical pushrod angle I could manage without installing pushrod tubes, plus more than I can mention on this post.

Rumble: I would think the machine work that may be reqiured would easily offset the cost of retrofit lifter. Of course I'm sure that that's what you're thinking too! :) I'm guessing that you dont want to go with a true Magnum block due to the head limitations? Fill us in! Could there be a way to tap into an oil galley and still run W-2's, W-5's etc?
