I have a stock 400 small block out of a 77 chevy truck i want to put in my 66 c10. it is basically stock with a 600 edelbrock and edelbrock aluminum intake. for now all i want to do to this engine is clean it up and get a different cam and lifters, and headers. i dont have the money to change springs or the converter. my question is what is the biggest cam and lifter combo i can put in this motor and get a good choppy idle but not sacrifice drivability. I know nothing about cam specs or engines in general. thank you for any help you can give me
