Re: Crate 350 in 85 k5 can’t get up to highway speed
Make sure weights are advancing.
Vacuum advance hooked up?
Wires arcing? How is the cap and rotor?
EGR hooked up? Closing completely?
Vacuum leak? Spray carb cleaner around and listen for a change. One at a time, pull off lines and cap them to see if the RPM drops.
Choke releasing completely?
