John,
So how do I explain a 68 block in a 67?  Is it possible that with it being close to the end of the model year that a 68 block was used?  Or were blocks allocated by calendar year versus model year?

Here's some additional photos of the additional tags.

Had an interesting find this weekend while I was doing some detailing.  I was doing some research on block castings, engine codes, and partial VINs.  According to the drivetrain info, the only block castings for the 67 L6 engines were 3877178.  Started getting really confused when I found my block to be what is suppose to be a 68 block (3921968).  The engine code matches my POP (F0626FM).  Some may say that the engine has been replaced and the engine code restamped.  I know for a fact that this isn't the case.  This is the same engine that came installed in the car in 67.  The only other numbers that are visible on the block are above the starter and adjacent to the transmission filler tube.  There are 2 plates: 1) CON2  2) 247.  I have no idea what those numbers could possibly be.  All of my documentation is original and I haven't bought a bogus POP.  Just curious if this could be a conflict with the drivetrain info.

I've become a firm believer in you get what you pay for.  But I don't want to get ripped off either.  Has anyone else used other products to elimate noise?

Does anyone know of a source for a 67 Rochester BV Choke Thermostat for a 250cid?  It appears that they're scarce as hens teeth.  Thought I had a source at Obsolete Chevy but they sold their last one in April.  Were these used on other models or is there a cross reference for the part number.  I have 3821564.  Can you replace just the thermostat spring or is it an entire assembly?

Great!  I'll try it.  Thanks for the info.

National Parts Depot ships theirs in a rigid cardboard tube so there's no chance of damage during shipment.  I've been very pleased with their service and their prices are much cheaper than Ricks.  No waiting on shipment either.  I placed an order and had the part shipped the same day.  One day shipment (which I didn't ask for) and their rates are very reasonable.  I do a lot of business with NPD.  Very curtious and knowledgeable.  Their link is:

If you've never used them before check them out.  I think you'll be quite surprised.

Sounds like the rolls are the way to go.  Everyone says to take your time when installing it also.  Where can you get the rolls?  Do they come only by 18" x 32"?

$400 for Dynamat cut for F Body.  Ouch!  Must be really good stuff.

I had my 67 restored a couple years ago.  During the process, it was put on a rotisserie and all of the undercoating was stripped.  When I replaced the carpet on the inside, I left the original noise dampener in place and installed the new carpet over it.  I also replaced the radial tires with the original 4-ply bias tires.  The problem is that now I get a lot of road noise inside the car; not nearly as good as when the undercoating was installed and also had radial tires.  I've read the thread on undercoating and it was applied originally by the dealership.  In lieu of having it reapplied, is there a good solution out there to eliminate the noise while keeping it as original as possible?  Anyone know if this was as evident on those that didn't have undercoating applied?

Does anyone have any idea how many of the original 67 250's are still around?  I imagine that it's hard to tell since even VIN numbers don't necessarily reflect the true engine if it's been swapped for a small or big block.  In my opinion, the market is flooded with 327's, 350's, 396's and Z-28 clones which makes the original 250 even more valuable these days.  I'd probably get smacked by a big block owner for saying that but when you look at the number of L6's produced versus the number you see at shows I think you'll agree.  I've kept mine as original as possible with the supply of parts dwindeling quickly as there is little demand out there for them.  And I doubt that is because the 250 is such a reliable engine that it never fails.  Even though it was considered a "grocery getter" you'll still get lots of comments from folks that appreciate the true originality of a well maintained original.

National Parts Depot shows a PF-25/PF454 and I believe this to be the correct filter for a 67 250cu L6.  At least that's what I'm banking on and using.

This is as good as I could get.  It's pretty crowded in there but hopefully once you locate the first hole, the other two should be obvious.

I've got a Norwood build 67.  It was found under the passenger seat and is in immaculate condition.

I've bought two sets from National Parts Depot that looked and installed nicely.  The only reason I bought the second is because the first set got dented after 5 years of usage.
