I am looking for info on front magneto drives for a SBC. Did anyone make a drive coming off of the timing cover? Would the drive gear have to be backwards? Anyone have any pictures?
one of my old dragster engines had one that was a summers brothers. they used a vertex mag base in the conventional rear position (no top on the base just a plate) this provided the needed dist shaft to complete the oiling cycle as well as a place for the tac drive to hook up to. the theory was (as I was told) that havng the timing off of the front was more accurate. they figured that the cam could flex/twist under load (?) giving false timing curves??? take it for what it's worth?

I remember 2 different styles. One of which was a straight mount like a mechanical fuel pump drive. The other had a right angle attachment that mounted the mag vertically.
the guy that bought my company(summers bros),is still making them with or without mechanical fuel pump provisions,but they are not cheap. summersbrosracing.com. frank.
