Upgrade my stock 350 for torque.

[69SCSS]

My '68 has a 195/260hp GM Crate Engine from 2013 in it. I swapped on a Performer Intake and 1405 carb. It runs good, gets OK mileage, pulls well, hell even spins the tires occasionally. I did a quick GPS 1/4 mile test and it did a high 14 at about 85. Not bad, really. But.... I want it to pull harder.

My real world expectation... I don't really go over 4k rpms, ever. So torque is way more important than hp. I want to upgrade the long block with a cam / lifter kit that will maximize low end torque, and if it runs out of steam at 4500, no worries. I have stock ramhorns and pretty happy with how they sound and work.

I looked at a COMP grind SK12-206-2, (https://www.summitracing.com/parts/cca-sk12-206-2) that seems good. I also saw the COMP CL12-210-2 (https://www.summitracing.com/parts/c...10-2/overview/) that seems good, but not sure that it might be too much for my small stock iron heads. I want to keep with in budget, so $250 for a cam swap is about right. Anyone have any experience with either of these or similar spec grinds for torque?
