Best fuel push rod

[greenmachine]

hi
I just switched from electric pump to the edelbrock 7123 pump (110 GPH) on my 440. I have a bullet mechanical roller cam. Is the comp cam 4646 the best choice of fuel push rod to go with? Thanks. Erik.

You need the rod with the bronze tip with steel roller cams. The 4646.

The previous rod mentioned is for cast flat tappet cams only.

Thanks guys. Ordering today. As far as install. Pull plug in block, feed rod in as deep as possible with assembly grease to hold deep in the block. (Does engine orientation make any difference, I.e at TDC?). Put pump on with grease on pump arm and reinstall plug on block.

that's it

If installing the pump you meet a lot of resistance trying to get the pump square enough with the block to get the bolts started, then turn the crank to reposition the cam lobe. (That was a long one)

Sorry, wish I knew what the timing of it is for the shortest pushrod position.

Best fuel push rod?
we use the same one as for gasoline

You don't want the cam on the high part of eccentric .

So here's the latest in my saga. I went to install the 4646 rod and roll the motor to find the lowest spot to make install of pump easier. Had my dad hold the fuel rod against the cam as I rolled the engine. He said no movement of rod. It's a roller cam. No eccentric?

I'd remove the pump rod and measure the length. I don't know how it should be but others do. edit length 3.220" There is a hex head plug below pump mount. Maybe get a wooden 4" or 5" long to test eccentric on cam to be sure its worn.

You can see the lobe with distributor removed.
