Ford Flathead dragster build

<< < (9/9)

RailDog:
New to this board -- I've been following your build -- very nice

Thought you might like to see my front cover mod for Hilborn pump

andrewb:
Nice mod RailDog. Did you drill/install a drive stud on the front of the cam?

Andrew

RailDog:
Yes -- cam snout was drilled for 7/16 fine thread allen bolt and a center made out of 7/16 bolt  was screwed into cam. Then cam put in block, Offy cover put on block and tapped with hammer to give center of drill hole. Then milled recess for pump flange using the center drilled hole.

Had to shave about .020 off cover surface to clear cam gear below distributer boss -- the offy covers have enough meat to just tap the 3 pump mounting bolt holes into the cover -- you have to rotate pump a little or use a clamp type coupler if you have a particular index position you want on the pump orientation.

Used allen bolt with a an washer under bolt head to set the pumpshaft end play.

I will probably use a 4 " pump extension on the new engine (blown) to clear the blower belts
