I have searched this topic and have been reading up on this for the past several hours, but I still have clarifying questions... a little background first. It's a 40 Ford with dropped axle, putting in an SBC with wilcap adapter to the stock trans and torque tube. I have a set of Chassis Engineering side mounts because I thought that would allow me to run a mechanical fuel pump. I read that the crossmember would need to be notched for this... can anyone confirm or deny? Also, the side mounts could cause exhaust routing issues on the driver's side due to the steering box... I suppose I could use block huggers, but ram horns look more trad.. So... with all that information, I'm leaning towards a hurst mount again, but It seems like it's about 50/50 on whether a mech. fuel pump can be used with this mount. I guess I'm confused... do the side mounts sit the engine lower in the frame thus requiring the notch in the crossmember? Also there is mention of spacing the hurst mount to use the mech. pump, but does this interfere with anything else like the lower rad hose? I also read a few comments of grinding the hurst mount for clearance... PICS OF YOUR Mech. fuel pump in a 35-40 would help. Thanks.
