| Post subject: | optimal jet size (van) |
I'm going to send my Holley 1945 out to a local carb shop for rebuild. Without direction from me to the contrary, they are going to jet it per original specs. Inasmuch as it is a lean-burn, I'm guessing that the original main jet is undersized, and the power valve oversized. Since it's a van, my only goals are torque and fuel economy. What direction should I give the shop re. jetting? (lean burn is intact, btw, but is getting swapped for HEI in a few years when it is eligible for Q plates. I'm keeping the 1945 until the next time it needs a rebuild--it has the appropriate port for a vac-advance distributor-- then hopefully, switching to a 1920.) |
