Original jets & rods
« on: May 25, 2010, 07:31:54 AM »
Have a 7045213 YA  and would like to know the factory jetting & rod sizes?
It has large main air bleeds .119 main body & air horn. It had 70 jets & 39 rods but that doesn't seem right.

My list shows that PN for a '75-'76 Chev/GMC truck, non CA, HD. It shows 68 primary jets and 32 rods. CP sec rods. You wouldn't think the large air bleeds would work at all with that small a jet but the rods are tiny in relation to them. Are you sure that's the correct PN?

That's the correct number, checked it again.
