Put the whole thing at TDC, TDC mark (1st scribe on crank pulley from left) on crank pulley inline with timing pointer. Check cam timing again, IMO put stock cam wheels on to set. If using stock cams make sure the dimple in the inlet cam is visible and lined up with the flat edge inside the oil filler hole. Knock pin on inlet cam should be at 12 oclock and exhaust cam 5 oclock. The 2 scribe marks on the cam wheels lined up with pressed metal line on backing plate. Pull distributor out and make sure lined up correctly and re-stab, do with dist cap off so you can be sure the rotor is still pointing at #1.
Dist being out is the most common issue when people rebuild these engines, i hold the rotor with my palm while inserting it and hold it slightly anticlockwise and twist clockwise as it meshes. The cogs are not straight cut and the rotor will turn.
The whole timing setup on these isn't hard. But needs to be right. You cannot check timing while cranking, so don't really know what you're doing there...
if it's not blown, it sucks
