Main Studs??

Yep, fill ur boots and do whatever YOU think is right for the application !
And so EVERYBODY should.

We Dyno everything we build.... we have to... in the presence of the Customer, to their satisfaction, BEFORE it leaves, NO exceptions.
Far too much liability with 30-40K 800hp-900+ hp Competition Wedge & HEMI Engines not to ??
and we enjoy the "residuals" when they come back for freshening every few seasons after 250-350 runs still in one piece.
That said,
We target our Mains to be less than .0005" Straight & Round, Yes, even on Cast Iron Stock Blocks.... for "our" comfort zone.
Align Honing is one of the most difficult Machining Operations to do well.
