I've got an '86 318 roller cam short block, cam reground by bullet with their HR259/316 lobe for int & ex, hughes 1110 springs, 2.2L retainers, mag heads, headers, eddie RPM air gap, and eddie 1406 600cfm elect. choke. runs fine year round in michigan, gets a little cranky on cold mornings below 15 degrees or so until it's warm.

I strongly suggest this cam, doesn't need roller rockers. mine's going fine with stock mag lifters, pushrods, and rockers.
