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!
