ok,thanks for the reply
engine casting date appears to be 24 4 90

if this is a magnum block you would need pushrod oiling plus don't the magnum motors use a pedestal type rocker similar to a chev ?
looking down where the oil feed port in the head is you can see the head bolt,ptting a rod down there only goes about 1 1/2"
