New to me, 72 K10 w/org 350 with about 140k miles on it. Runs ok but a bit ratty. New plugs, wires, cap (has later HEI distributor). Suspect Qjet carb needs help but if functioning for now.
It appears to have a replacement radiator in it which leads me to believe there may have been some overheating conditions in its past.
Ran compression test on it & all cyls good at 90# except cyls 2 & 4 test to 20#.
Checked rear differential yesterday and found it about 2 qts low!--suspect the PO did little or no maintenance!
Been along time since I played around with older engines and do consider myself a novice when it comes to diagnosis of engine problems.
I suspect possibly a head gasket problem between the two side by side cyls.
Any help, thoughts or ideas reference this problem would be appreciated!!
Thanks in advance for your help!
