My buddy had a pair of 370's, that were rebuilt and upgraded at some point years ago.

They installed crane 134561 cams (236/246 .553/.555 114lsa), and roller rockers. however, they left the stock cast iron manifolds, stock mag intakes, and quadrajet carbs. One of the engines dropped a valve, so we are rebuilding it, but now adding stellings headers, holley 750DP, single plane intakes. I think the engines should wake up with the new exhaust, intakes, and carbs. hopefully. That was alot of cam for stock exhaust.
