Camshaft help and advice
« on: May 06, 2015, 01:03:03 PM »
Hi Matt,

 Hope you or some of the others can help.  I'm looking for a cam for my engine build. Engine is a SBC 355ci, will be running a 6-71 supercharger' mechanical injection. Fuel will be Methanol. I'm thinking a roller cam would be a good idea to reduce the maintenance, not sure if that's right.

Ponti:
 A roller cam is a good choice. The specs posted by the other guys is spot on. Spend good money on lifters and rocker arms.
Cheap lifters will fail and ruin everything else you worked hard to buy.
I suggest the Crower Hi-Po roller lifters.
