High torque 360 LA build camshaft recommendations

Hey Brooks, that 350 build was a blast from my past...
Many moons ago my buddy started pulling his 67 Camaro race car around with a 66 Impala Wagon 283 2bbl/PG/2.73. He bought a flat top 350 short block, cleaned up the 283 heads and bolted them on with a mild hyd and the original intake and carb. Guessing the open trailer/race car weighed 5,000 ish. It worked like a champ and didn't roll over til about 4800 r's.

I'd love to see how a 360 would perform like that with the small heads? If you could find a SP/2P intake for under that TQ, i actually have one i'm not selling :), i think it could be a great engine for what he's looking for.
I've got one of these hanging around too! Lol.
