Re: My 70 c20 dies when put in gear
If your vacuum advance is hooked to ported vacuum change it to full manifold vacuum. You may have to get an adjustable vacuum advance unit & adjust it to come on with lower vacuum. With a performance cam you have less vacuum. What are the specks on the cam at .050. & the lift. If you have too radical of a cam it will not work good with an auto. trans. unless you use a high stall converter. They are not pleasant to drive. Your float level in the carb may be too low.
