Thread: dizzy not reaching oil pump shaft,.

Tweet

All stock chev dist are same length--sb, bb, and tall deck all have same length

do you have a spacer between the main cap and oil pump to lower the pump for a deep sump pan?

Tall deck truck manifolds had the dist setting lower----A few companies now make dist with sliding collars, but if your shaft doesn't mate with your distributor in the area of the boss you are asking for an big oil leak all over the track/road and a trailer /tow truck ride home

no jerry the old tall deck truck did have a longer dist i can not tell you if the new hei is longer but the older points ones were. yes if it has the oil pump with a bottom pickup them it will need a longer oil pump drive

there is no spacer between the cap and pump, dizzy gear is meshing fine with the camshaft, the oil pump shaft measures 170mm, could it be the shaft or the pump is a reject and not quite the right dimensions, or perhaps a different make would be slightly longer, 5 or 6 mm on both would solve the problem, i would be unlucky to have both of rubbish quality!!!, mike.
