    ARP bolts
    « on: January 27, 2008 - 09:18:20 AM »
    I`m upgrading my 383 engine
    I wonder if it would be necessary to go with ARP bolts in the shortblock?

    calculated CR 9.98
    mopar purple 284/484
    915 heads with bigger valves
    Mopar Muscle did a similair build and they had 451 hp on the dyno.
    However, they used a comp cam ,509 lift

    If you are going to spend the money on bolts, you may aswell buy studs instead for a little bit extra.  But in reality with the compression and cam selection, you really do not need to upgrade the bolts buddy. :2thumbs:

    I would at least put ARP rod bolts. Other than that, you should be ok.

     :iagree:
    ARP rod bolts are a must.  I would be careful with using head studs, as Chryco has said the heads cannot be removed while the engine is in the car if head studs are used.  I am not sure if that is true of a 383 but would check into it before using them on a street engine.

    I believe that it`s true at least on the drivers side.

    The head bolts are torque-to-yield, aren't they?  Once used and tightened to spec, they cannot be used again.

    So I`ve heard too, but I`ve never replaced any head bolts before.

    Old engines do not use a torque to yeild head bolt & they can be reused with no issue
     personally I hate the TTY bolts just give me a stronger bolt & a consistant torque setting

    Some head studs now have a hex shape on top of the stud, this way you can remove the stud in the engine bay.

    I was told on new head bolts, thats is only $55 or so, if you can swing it, do it.
