Morning all,
I am getting really BAD gas millage. Something like 10 or less to a gallon. I have a four barrel Holley (1850-2, 600 cfm) on a high rise manifold. This is on the highway too. I know that 4.22 rear end does not help but man.
The engine is a 260 bored .030 over with a "hotter" cam. I do not know what cam it has at this time.
My question is - you guys running a Holly four barrel on your 260, what is your primary main jet size. I have not cracked open my carb to see what I have but I would like to know what I should have. I do have the original Autolite two barrel, will the primary jets from it fit the Holley?
Thanks,
Duke
