Bought a 1951 ford panel van and it has a 1960 truck y block (B9AEF with COTE heads) and transmission.

Rebuilt the Holley 2 barrel but the motor still ran rough. Pulled the valve covers to adjust valves but found out that the external oil line feeding on the passenger side had plugged a long time ago and the rockers on that side where dry and shot.

Found a local guy that has two ford trucks (63 & 64) with y blocks he is planning on not using. He told me I could have any parts off of them I wanted. I grabbed a rocker assembly off of the 64 and got my panel running and driving.

1) is there anyway I can get the engine to oil on its own without pulling it apart? The external tubes are hokey looking and have already proved himself to be in adequate with this motor.

2) if I do end up building a motor would there be a better one of the three truck motors to use as a starting point (60 vs. 63 vs. 65)?

Any advice would be appreciated
