I am considering the same thing on a /6, I think I gapped the rings "by the book" when I put mine together. If I turbo mine im only looking for 6-8 psi at most. Would that be too much boost for "book spec" ring gaps?
I know that most push the "blow thru" setup over the "draw thru" but I'm looking at draw thru since I'm not looking to push it that hard largely because I put "rebuilder's" (oe replacement grade) cast pistons in it when I rebuilt it.
And im not interested in 11 sec 1/4 mile times just looking for a "little more" out of a small motor in a truck body ...
Not trying to step on the op's thread but thought what I'm wanting to do might be relevant to what they are wanting. My questions might relate to their build.
