camshaft for mild 340

That summit cam is REALLY close to the old 280/480 mopar camshaft. It's cut on a little wider LSA 112 vs 110 IIRC

Another inexpensive camshaft that works well is the old 214/224 cam. Faster lift stuff is nice but also has greater potential for failure and other parts not playing nice.

Pick your parts, pay your money!

Exactly! Slow, reliable ramps have their place!
