I recently purchased a 1972 Lemans the car is an all original 350 auto with a four barrel. Here is the question I like traditional but I'm all for improvement. The car does not have to be original for me. How do you know what parts to up grade and what just to replace? Money of course is an issue. This car is an a/c car. Is it better for me to buy a newer meaning improved not original radiator, or stick with stock? I don't want to spend a couple hundred dollars and in a couple month be like man I should have changed that. I drive this car as much as possible. I have no desire to make it into a show car. It is for straight fun. I live in New Jersey so A/C is manditory for me. Any hints on places I can go to to speak with people about profomance and other up grades. You know what carb, What type of pipes. I only want to make these purchase's once and from the right place.
