will i get better proformance with m hangers and dr rods in a lg4 motor with edlebrock air breather and flowmaster exhaust?

 

If it's got the stock CH rods like the LG4 carbs came with the answer is usually yes. You probably won't find an M hanger from the aftermarket, but you can probably find something around a K which will be plenty close.

 

M-hanger and DR rods were stock in alot of fullsize truck/van 305s. They made about 30 HP more than the the LG4 of the same year. F-hanger and DR rods will run even better. 90% or more of your driving will be on the primaries. The primaries are often very lean at heavy throttle and should be richened up.

 

i pulled the hanger & rods that wre in the car, S hanger but no number on the rods. i put in the M hanger with DR rods, it doesn't bog. Is the S hanger better than M hanger for DR rods?
