As noted in "The abuse continues..." the nature of this particular project has taken a rather dramatic turn. It was fun for about 10 seconds to think about turning the car into a full-blown racer, but as I mentioned in that thread, if it's not street-driveable, it's of little use with the nearest track being 120 miles away. But around these parts, with no traffic jams, few stoplights, and lots of open road "street driven" is a looser definition than it was when I lived in Atlanta.
With that in mind, I made a phone call tonight and talked to Steve at Lunati Cams about the car, and what I'd like to do with it. Told him what I had, and after he recovered from almost swallowing the phone, he agreed that with the low compression, the already-high recommended powerband would probably be even higher with the low compression. Having said that, he asked if I was going to try it anyhow. I told him I'd considered it and asked him if he would. "Oh
hell yeah! Run it with that monster in there and see what it'll do, assuming it don't hit the pistons. You've already got it, why not? I'd run the shit outta it at least once at the track." So while I did order a different roller cam from him, we'll give the one that's in there a shot... and try to heed his advice: "Come out hard at around 5,500 and your foot in the rugs, man. It prolly ain't makin' no power at 44 with the low compression."
The cam I ended up ordering will be "a lot of fun" according to him. It's another solid roller, this a custom grind: 254°/262° @ .050", 287°/295° advertised duration. Lift is .621" on both intake and exhaust using the 1.6" rockers ("'Course, you know it ain't gonna be that high with them wacky pushrod angles in a small-block Mopar, but you can tighten the lash if you want"). The powerband is accordingly lower, he figured with my heads 7,300-7,400RPM would be a good shift point on a 7,500RPM redline. Having run stock bottom ends in that area, I'm comfortable with that. What sold me is that he said it'll light up in the low-3-grand range. That'll save on some driveline shock as well as clutch abuse. Still a pretty-serious cam for a small-cube engine, at least in my mind.
"Man, when you call back to order that turbo cam, ask for me. I wanna be involved with that one."

Well, Steve, let's see what happens with this roller and we'll go from there.
