EDELBROCK PRO FLO 4
I have an older version and had to clearance for the distributor housing. I recommend reading the updated instructions on the Edelbrock Pro Flo 4 forum. There is an apparent change in the required coil that was previously recommended by Edelbrock (22741) that can due damage if used. I have to contact tech support and get a return authorization. I will add that my Vintage Air Sure-fit kit for 1968 B body and LA small block with EQ heads, came with a 1970 and up LA engine bracket kit (162774) that fit my early water pump (fabbed 2 spacers) and cleared the Pro Flo 4. I haven't lined up the pulleys but they can be shimmed if necessary.
