440 Intake Clearance?!?!?!

I did run a 440 with stage6 heads and M1 intake with a 4150 holley and 3x14" aircleaner in a 68 dart. That combo did not clear the stock hood. But with a stock cleaner or a lower filter it might... Also i don´t know if there are any difference in clearence hight between the 68 and the 73 dart??
