I have a 79 c10 with a sbc 350 and i drive alot of freeway to work. After about 15-20 minutes of 65-70 mph driving the truck will start ticking and develop a dead miss. Clears up once i get off the freeway and lower speed. I know somethings obv wore out but im not sure where to start. I drive a truck so i dont have alot of time to troubleshoot. Am i looking at a bad lifter? Cam? Oil pressure and temp is good btw but oil pressure needle does begin to "jump" when it misses. Not sure if its relevant. Need some ideas thanks.
