"Rule of thumb", .001" of clearance for every 1" of journal (mains). For rods, we've found the Pontiuac to "like" .003. They live. What else can I say?

We "mock up" the main tunnel and measure it. If "round and straight", not a problem. We've seen VERY few blocks needing align-honing after stud installation. Pontiacs are a little "better done" than Chevys. It's "standard procedure" to do this to a Chevy.

Sarge,

Where did you buy that crank? I've only had three of the forgings through here, but all were dead-on size. Have another on order. We buy them from a reputable warehouse that sells the entire Eagle "line". It may not matter, "where", but it does with some Edelbrock stuff, so it's worth the question.

Butler. Stroker kit. I trust this old guy and it confirms what both my buddy and I saw when we checked it. Other mains were about .001 out.

As far as the line bore, I gave him the measurements and he saw they were ovaled, "like an egg" I believe is what he said. He is proud of the line bore outcome, said it is dead on.


Another thing I noticed on the mock up, the nuts on the rear main studs don't thread all the way, about 2-3 threads are still seen on the nut when tight. ARP. Studs are finger tight, should I back them out of the hole some so I get the stud a couple threads out of the nut?
