440 Engine Knock

tooslow said
Howdy,
I hear a knock and the frequency makes me think it is a main bearing . Engine has 800 miles on a pretty Hot rebuild . I already started pulling the engine I would rather pull the engine and check the bottom end vs driving it and having it grenade . Plus its no fun driving it knowing something may be wrong.
Question
Would someone help me with a procedure to check Main and Rod bearings while I have it on the stand?
> I want to disassemble as LITTLE as possible
> I know how to assemble and engine , I know you have to return all caps to same journals,torque ect... I have Plastigage and all Indicators, calipers, dial indicators . ect..
> I am assuming all of the ARP bolts are toast once removed , Is this true
Thank You for ANY help
Go Dodge !!

I want to make it to Ohio with my 69 Dart in August, I have to get moving on this

ARP says three uses for the critical stuff like rod and head bolts. Personally, once an engine's been put into service and beat on I just replace them on the next build-up. I do understand they're costly and, believe me I've done my share of re-using even factory bolts without issue...if your ARPs were only used once I wouldn't sweat it unless it's gonna see some hard running. The guys have offered some good ideas, I'm not sure how conclusive an investigation will be without disassembly. I'm with the kimmer I would get with the builder before taking anything apart.
