350 built for torque

[unstable]

I would like opinions on this combination.

Buy L31 vortec head long block. GMPP 350

Edelbrobk Rpm air gap intake

Comp cam XR264HR .212/218 lift .487/495 (roller lifter)

Comp Magnum roller rockers.

Hei Distributor

Holly carb 650CMF

Alternate cam would be comp XE262H .218/.224 lift .462/.469 (flat hydraulic

lifter).

I'm looking for a daily driver with great low end torque. Would this

combination produce what I'm looking for?

The long block is listed with 9.4 compression and 64cc vortec heads.

Which of the above cams will best satisfy the need for low end torque?

If this is not going to make low end torque, can anyone recommend a better

combination.

What would be the estimated HP and torque with this set up.
