Tom,
Yeah, the pistons are likely to be the bugger. Neither KB or
Silv-o-lite show anything for the 273. If you absolutely have to have
pistons, Egge is probably the way to go. Diamond will build you about
anything you want for between $600-800 but...

Steven,
Thats really good food for thought. 3 5/8" Bore Pistons will be more
difficult to find. But rods are all the same length.
As I price things out and see what I can afford, It helps keep things in
perspective.

Yes, it wasn't a tough call to make. By the time you buy the new
bolts, run them to the machine shop, they do all the work, you go back
and pick them up, they are STILL a 40 year old set of rods. Match the
lighter rods with lighter pistons and you can shave a bunch of weight
off your rotating assembly.
I have my originals all nicely boxed. My grandkids can e-Bay them in
50 years.

When I built my engine I found that the cost of reconditioning the old
rods was barely cheaper than the Eagle SIR6123CB rods. Plus they were
115gms lighter, 50% stronger and came with the ARP fasteners included.
Seemed like a no-brainer to me.

Tom,
I would not arbitrarily replace the wrist pins - they are either
good
or bad. I've personally never seen a lot of bad wrist pins. And if
the rods are bent, you can usually read that in the bearings on
tear-down.
As far as rod reconditioning, I would base my decision on how you
plan to use the motor. If it's just a cruiser, it's probably fine.
If you're beating it up and down the 1320, I'd definitely have them
reconditioned and install new bolts. Rod bolts are only good for 3
torquings - each time they are torqued they stretch a little and
after repeated stretching they work harden and are prone to failure.
That said we used to build what we called "grenade motors".
Basically pull it down (383, 413, 440, didn't matter), clean it up,
berry brush the cylinders, swap banks on the pistons, and put it back
together.
Screw on a high volume oil pump and go racin'. Funny, we never
grenaded one. Fastest one I had ran 11.40's in a 3200 lb Fleet
Special with a hydraulic camshaft and a six-pack, of all things -
shooting ducks all the way through 3rd gear. A couple of weeks after
that we were pitted in front of Mr. John Tedder hisself and after
looking the car over he said "you should get rid of that six-pack".
I had a cast iron manifold and a 750 Holley center section in the
truck that we had cannibalized for parts for the six pack - we had
the 4bbl up and running before first round of eliminations. We won
both bracket two and "King of the Hill" that day.
I'm gonna have to find that picture and put it up on my Facebook
page
:)
Anyway, if you're going to have the rods completely reconditioned
(new bolts, straighten, grind the caps/resize and the whole nine
yards) you may want to compare prices to a set of aftermarket H-beams.
I've been buying them on eBay when I can get 'em cheap ($250-$300 is
my target price range). Have had equally good luck with Eagles and
Scat.

Subject: Rod Reconditioning or Not?
When I disassembled my '65 Block, #6 rod had spun bearing. I have a
spare rod from another engine, in sme condition as the other 7 rods
that I have.
I plan to turn the rod journals crank before I put it back together.
Should I just replace the wrist pins and use the rods as-is, or must
they be re-conditioned? The block has about 80K miles on it. The
extra Rod I have was reconditioned about 2000 miles before it was
taken down.
Thoughts?
