Mild cam for my '70 burb

[zac]

OK, this isn't very exciting, but it's the middle of winter, so what the hey. I'm building a new 350 for my '70 K10, the block is on the stand, I'm sorting through the crank/rod options I have. This will be a basically stock rebuild. The heads are still at the machine shop, so I'm waiting on final word there, but they might be the only thing a little warmer than stock. A little. My truck has a a 465/205 combo and 3.08's with 31x10.50 tires. We use it mostly on the highway as a family driver, it tows nothing heavier than a fishing boat. I've had pretty good mileage even with a terrible engine, so I'm hoping for even better with a new one, especially with $3+ gas. I've looked at the High Energy series from Comp Cams, wondering if anybody has any recent experience or ideas with what I should look at, or not look at. I haven't bought a new cam since I had a mullet hairstyle like all self respecting kids. Hydraulic flat tappet cams are not all the rage now, are they?

I know about the Engine/Drivetrain board but like the more relaxed atmosphere here.
