Hi guys. Can any one give me an idea of what size jets and power valve to run in a 350 holley on a red 202 in my LC Torry? It runs a warm head, extractors and 2' system and is auto.
Thanks in advance.....Brian

59 jets and 5.5 power valve.
the clearance of the powervalve is proportional to your diff ratio / cam, it should never be touching at idle.

Old holdens brought on the spot, quick decision, cash paid. |

The power valve number is what vacume pressure it turns on at. So the lower the number the later it will come on as manifold pressure drops as you acclerate.
But at full throttle they all comeon no matter what.
