I've ran motors like yours with Mopar brand aftermarket Ducitle iron main caps and ARP main studs with forged H beams steel rods like yours with .030 clearances there on a street and strip motor revved up past 8200 RPM when a trans yoke broke with no witness marks afterwards More clearances there is better, for a drag racing motor that is not going to revved past 7000 RPM much I would call it good That is based on actual clearances with feeler gauges stuck tightly between the two rods in the middle between the rod cheeks to force both rods up against the crankshaft Mr.Cab Racing and winning with Mopars since 1964.
