Cam for torque question

I like the looks of that Crane. Did you run it with headers? If not with stock or 340 manifolds?
Both times I ran this cam was with headers on stock 318 & 360 heads furtherly equipped with;

Open air cleaner
4bbl. (600 - big TQ's)
Dual and single plane intakes. Dual highly suggested.
1-5/8 headers
Low compression @ 7.8-1 up to 9.25-1.
Low and high stall OE converters
4spd manuals
3.21 gears up to 4.10's

An old member here used this cam in his gutted track only Duster and ran 12's.
I ran the best of high 13's in a heavier Enbody.
