Jac, I am still continuing to learn, hence my questions, so apologies.
They reckon when you stop learning your dead, as I don't know who 'they' are Ill take some comfort from that and keep on learning myself
So whilst I have a D1ZM Mexican block the stamp date on the block is later than the D1 would suggest. It wold put it in the 73-76 range, which would give it a 8.229, rather than the 8.206 consistent with the earlier blocks? Does this not then in turn correspond to the 0.034 clearance that I am currently seeing rather than the .016 in the earlier blocks? That's why I asked the question above.
Sooner or later ( preferably soon ) you have to stop listening to everyone else-me included- and actually measure up the parts you have and decide on a course of action for YOUR motor.
Clearly, I would like to only have to take the block for decking once. Ideally, I would like to get this into a position to rebuild early December as I am having some time off from work after surgery in a few weeks (sinus op)
