Fuel Pump Eccentric and EFI
I have a new Ford crate 351 that I'm in the process of converting to EFI for installation into a 96 mustang. I'm pretty new to the 351 (the mustang had a 4.6) so I'm learning as I go.
The motor came set up for carb, with a 1 piece eccentric for the mechanical fuel pump. I'm installing the Explorer timing cover (because I'm using the 94-95 mustang short water pump) and the timing cover doesn't clear the eccentric (the eccentric is about 1/2" to tall). This wasn't really a surprise. Here's the questions:
Can I remove the eccentric without worrying about it causing a balance/vibration problem with the cam? Is there some sort of eccentric washer I should be replacing this with? If so, I can get it where?
The dowel pin for the timing gear and eccentric is 1.5" (not 1.375" like I would have expected from what I've read). It sticks out .25" from the timing gear, so if I remove the eccentric, I either need a large .25" thick spacer washer that I can drill a hole into to replace the eccentric's thickness, or I need to cut .25" off the dowel pin. I've checked the bolt, and it will go in far enough to snug the timing gear down properly without the eccentric - although I think I need a larger washer to properly hold the timing gear so it won't shear the dowel someday. If I go the shorter dowel pin route, I'd prefer to hang on to my original, and get a 1.375" and cut it. I've looked and can't find anywhere that sells just the pin. Anyone have a source?
Any other ideas on best to deal with this are welcome.
