Re: [Chrysler300] 1962 383 Build Questions...

Matt , generally any bolt  used for fastening ( not head bolts) needs to enter the female thread at least as much as its own diameter. 150% -200 % of that diameter is much better , if tapped deep enough . . So you can figure that out . Buy boxes of grade 8 hex cap screws  and lock washers , in a few sizes , will cost less and far less time than trying to do this to some exact spec number of single bolts  . Some holes may be tapped blind forcing slightly shorter , some bolts will have flat washers and lock washers . 

Someone like ARP May have B block bolt kits with better , but possibly non stock looking fasteners , maybe a listing of those helps  you to 90 % but engines vary . Holes into water need sealant on them . I use stainless steel often , have boxes of the sizes commonly used . See Amazon  .. Albany County Fasteners very good , great prices . 

studs on exhaust manifold would have to come from auto supplier or ARP

Good luck , John

If any knows answers for any of the following; that would be grand!

• Intake Manifold Bolts - I know there are 8.  Anyone know the sizes?  Some are longer due to the air conditioning brackets.
  
• Water Pump Housing Bolts - I know there are 6.  Anyone know the sizes?
• Thermostat Housing Bolts - Anyone know their size?
• Valley Pan Cover Bar Bolts - I know there are 6 of them.  Anyone know what size they are?
• Valve Cover Bolts - I have the 6 bolt covers.  Anyone know what size they are?
• Exhaust Manifold Studs & Nuts - Anyone know what sizes are needed?  I know at least one of them is longer due to a bracket attaching to it

And Finally.....

• The Rocker Shafts & Arms that I have....
• They have 4 Spacers; Is that correct?
• I read that some had 5 Spacers; 2 that were thicker that the other 3?
• Which is correct?
• And / Or - If I wanted to buy new, stock Shafts & Arms; who would you suggest?

Thanks!
