Dart Little M sportsman top end oiling issue SBC

[Matt S]

I had the same concerns when I primed my Little M for the first time after it was built. It took MINUTES of spinning the drill, and rotating the motor 90 degrees, but eventually, I got oil from all 16 rockers.

I would say cut lifters,just takes small groove,I use 1/8 die grinder or a thin cut off wheel,you just need a few thousands deep from oil band to oil hole,another thing to look at if you have small base circle cam is to make sure oil band is lined up with oil galley,if band is below oil galley only time it can oil is when lifter up on lift,if that is the case you can cut grooves or cut chamfer on oil band so it matches up to oil galley when lifter is on base circle.
SBC should oil all rockers without having to rotate engine.
Any mods you do,do carefully doesn't take much to go from no oil to flood.
