The problem there is that nobody makes a self aligning 1.7 ratio SBC roller rocker. It can be done, but it takes work.

IMO
See bold comments that are embedded.

Beyond that I did the cam first with 2.93s and 1650 stall I had put in at rebuild was a stock truck converter, with stock exhaust manifolds one 14.9 slip. I gained almost nothing. Later did the 2800 stall and gained a lot at the track14.1 despite a swap to lower octane tuning, did the 3.42 gears and gained a little at the track 13.9 at a quicker track but it made the stall more drivable so it was worthwhile, then the headers and gained a lot again 13.2 first night out more left in the combo if I was going to keep it like this.

I did it assbackwards, do everything else first unless the motor is coming apart for another reason and the cam is easy at that point. Don't be afraid of a little gear and stall. My wife has still gone and picked up Grandma for dinner with my car as it sits now, hell the Mickey Thompson ET Drags were in the trunk at the time :D . Labor Day we hooked up my small fishing boat and went on a 500+ mile weekend trip to my parents and it is not highway travel.

I have a lot to learn? yer damn right! thats why I'm posting. I have 3.73's in the mail, V-sptimgs and 1.6 rr's on order, headers in the making and a catback/intake already done. after the other mods, a tune, and then an edge 25-2800 are in the making. I was more curious which cam keeps 'stock cam' 2500-5500 RPM manners with more pull. I know theres a lot to learn, but I'm not going for E.T.s, I'm going for 'fun to drive and bash hondas'.

whats a cam with more overal pull that would be shifted around 5700-6000.
You really need to define 'pull'. You looking for highest average torque increase, highest horsepower, highest peak torque, what?

The stock cam......if you have decent valve springs and higher ratio roller rockers.

The ZZ3/4 cam or the Crane 227 cam would fit the bill quite nicely as well.....
