do you have the stock stamped steel rockers or the 273 style adjustable rockers? If the latter, run em!
What are your actual goals for the car? If its just to be a cruiser, leave it alone and save your money.
Ifs its about significantly improving performance, installing a “ real” convertor in the car along with a performance cam will make a world of difference. Huge difference!
If your just wanting a street brawler, i would install a mid 240’s @50 solid cam and a tight 8 inch convertor.
It would wake up in a hurry, and in that case, the intake would become way less of a liability. And drive just fine on the street.
You really need to post specifically what you want the car to do
