First for the linkage to clear you need about a 3/8ths spacer, they use to be pretty easy to find but I haven't seen one in years...But 1/2" ones are avalible....Also if your running a stock intake you should have more room than you seem to think.. Try losely wadding up a few balls of tin foil & place them around your aircleaner & shut your hood, that will give you an accurate idea of how much room you really have...

BTW you'll need a holley/mopar throttle adapter...
