Fuel Pump Push Rod

[mqdirtracer57]

I am installing a fuel pump push rod in a 604. I elected to go with a bronze tipped comp cams version. I have a stupid question...Both ends are bronze tipped. One side has an 1/8th inch long section and the other end is inserted flush with the tube. Which end goes toward camshaft? I worry about it mushrooming if I install incorrectly....thanks for any help

The 1/8 to the cam. Bill

Thanks Bill...That's how I have it,just wanted some reassurace... I had one mushroom with a flat tappet cam before that was professionally built. I am glad that there are guys like you in the racing world for keeping us racers informed. Do you sale matched valve springs for a 604 over the counter?

I sell the springs when i can get them,at this time its averaging 6 boxes of springs to get one set with some pressure I dont have any good sets in stock. Bill

steve have you had any success with chp fuel compared to other fuels? we dynoed 604 on dts dyno last week and about 3 hp was the difference between chp and sunoco 110.
