1967 273 V8 change to 6-pack carbs
Putting a 6pack on the 273 is a waste of time unless its a highly modified motor made for the drags,and even then it would be a 4 barrel carb or dual 500cfm,s on a tunnel ram turning 8-9 grand.If the motor is running at 100%V.E. at 6000rpm,it only takes in 475cfm,so take off 15% for the average street motor tuned to the nines.It would look neat if you installed it on 340/360 heads and only ran the center carb,as the middle carb would be more than enough for your motor by its self.The ports on the 273 heads are to small for that intake and would do more damage than good.Find a 340 or 360 and install it on that and have a blast with it.Mrmopartech
