it all depends on the base you use you can get the short ones or the longer ones. one carb or 2 or blower or injection mounted i like running the dual 4's >long style> one on a single carb just looks better then the <single carb> midgit one. check jegs or summit......scooter. heck i had a hillborn style one on my 79 malibu wagon with a stock 305 with a 142 mini blower on it was for fun BUT IT STILL HAS TO BOLT TO THE CARB!stick your hand up the back and tighten the nut down yes its 5:14 am yes i just got off work yes im tired and heck yes i am rambling
