    Using threadlocker...

    in Buick - Post War

    Ok Thanks,

    I didn't use any thread locker of any kind. Your manual has the same information as in my 54 manual.

    It doesn't say what to torque the cam thrust plate or Cam gear to...

    The 3/8-16 has a wide variable in the charts, I went to 36 Ft LBS on the thrust plate and 58 on the cam gear.

    Thanks,

    jerry

    1954 Buick 322

    The manual doesn't have torque specs for every bolt...

    Should I use any thread lock on the cam thrust plate bolts or cam Bolt?

    I saw a chart stating the size of the bolt dictating torque value (thrust plate bolts are 3/8 so torque to 33 ft lbs, but seems like it could easily go more. But is snug)

    Cam bolt seems to be a 7/16 so charts says 58 ft lbs torque.

    should or shouldn't I use thread lock anywhere?

    these are the original 60 year old bolts.

    Thanks for setting me straight!

    Because I'm clueless (see edit history)

    60 year old nailhead is starting to go back together, do I need to use ARP or can I use regular "Grade 8" bolts. At least on the heads and mains, rods too?

    I am pretty sure I don't want to reuse the original bolts, I'm sure they have been torqued to spec at least 1 time.

    This is not for a race car... Just a old 322 trying to put together.

    Head casting number

    I am wondering if I can swap heads for my build, I'm trying to write this in the simplest way...

    I have block #V5229585 in the shop that came with head casting #1165649.

    I have block #V8461335 in my shed that came with head casting #1166349.

    The #1165649 driver side head is bad... Can I put the #1166349 heads into my build?

    do the pistons need to change?

    thanks,

    jerry

    Thanks Willie,

    I was at the shop yesterday and they look pretty close to the originals to the naked eye. I think the box said "Builders Choice". The shop purchased them after re-conditioning the block. It had 1 pretty badly scored cylinder and the usual wear in the others. The cylinders ended up at 40 over.

    Looking for more advice...

    Just following up... The block went to the machine shop, crank ground and polished to .010 and the cylinder walls needed to go out to 40 over. It's getting the full treatment, new pistons, cam lifters.

    quick note, most of the cylinders were all worn equally, the score line went away at about .020 but the #2 & #3 cylinders had additional wear, which is why it ended up at 40 over
