Hesitating 383 cid
Thanks guys!
The jettings are .110 in the primary and .107 in the secondary.
Metering rods are 070x037 with pink step up springs.
Did some investment in a 3.91 gear kit to install this winter.
The 2.76 was in the rear when a I bought the car, have always had the intention to replace it with a 3.23 or lower gear.
