What's that 289 in? Weight, gearing, tire size and planned use have a lot to do with cam selection.

it had a 302 roller block with 2 different truck heads, ( stupid ) i know but i got it that way, i was able to get a fresh 289 .060 over with the brand new intake and carb that i listed before for 200 bucks, going to put the e7 heads on and get a little bumpy cam for the sound and just cruise around in her.

a lopey cam, stock heads, and a 600cfm carb might not be a lot of fun to drive, especially in a truck.

don't get me wrong, i understand what you are after, but from my experience, a 600cfm carb is a lot with a stock head-ed SBF.

My advice:
Shoot for duration of 210-220* @0.05" lift, a 500cfm carb, spend some money 2000 or 2400rpm stall converter (depending on your rear gear), and enjoy the sound of all 4 barrels open at one time ... and forget about they way it sounds at idle.

If you are going to use a roller cam, you could probably shade a little higher on the duration, but if you get a long enough duration that the engine lopes, you may find that your truck is a lot less fun to cruise with, unless you go pretty deep with the gearing, and go with a pretty high stall converter ... all of which can get old on the street.

Shoot for a cam that will give you about 80% of your max torque from about 2000 rpm to about 5500rpm, and it will feel like a freight train when you lean into it.

Agree you do not want a big cam... big cam and heavy vehicle makes no fun. One thing to check out are Comp Cams "Thumper" series. They are made to produce a noticable idle but smooth out with a little RPM and produce good mid range torque. One of the smaller Thumper's may fit the bill for you.
