Very random question but does anyone happen to have an old, unwanted piston from a 496 big-clock Chevy engine? One will do, doesn't matter if it's holed, dirty, scratched, been used for an ashtray for the last 30-years or whether the piston rings are present or not, as long as it's roughly dimensionally intact. Has to be a 496 and no smaller. Shipping looks to be about $20 for such an item to where I live. Naturally I'd pay that. It's for a design project.
Such items are unobtanium where I live.
Let me know by PM if you can help. Thanks.

I have 14 unused said pistons in my shed.
You can have them they are mine :banana:

You drive a Morgan 3-wheeler! :banana:

I thought your shed was full of books? :devil

His shed is full of tools except when he is here. :rofl

Its full of sailors from the Royal Navy :old:

Perhaps the 496 was something of a rarity even in the US?
Found one on eBay. Shipping & import duty doubles the price unfortunately. Plus it's new. Didn't want to deprive someone who needed one for a real application.
Anyone know anyone using one for a door-stop? I'll trade you some advanced ACM training :banana:

Good history here: http://garage.grumpysperformance.com/index.php?threads/which-496-bbc-engine.12291/
Never even heard of a 496 until this thread. Thanks!

:rofl Trust me to pick the obscure one thinking it's normal. Lots of boat-applications apparently.
Cheers Oldman.

It was used in trucks too. The piston will be around .060" larger diameter than a 454 if you have one of those.
-
Standard 454 piston is the same ... it's the stroke that makes the diff. .060 is a common over bore when refurbing an engine block of any displacement.
-
Ohh and the standard 454 piston is 4.25".

Never had one. Knew you could make one, stroked 454 bored .060.
On the bored engine the 454 heads will fit. Will 454 heads fit on an actual 496? :)

> 4" pistons :rofl Fantastic!

I have a piston from a Kieth Black hemi,it’s kinda melted and has part of a valve inserted into it. Not sure of it’s size but I think the hemi was north of 500 ci and no you can’t have it,took over an hour to get it out of what was left of the block.
:salute
-
I dropped a valve in a 327 once. Buried in the piston. Barely marked the head.

LOL… this hemi was in a drag boat that blew up just as it launched,a good portion of it is at the bottom of the lake. It blew several rods out the side of the block and the blower only stayed on because it was tethered in place.
I was able to grab the piston as the engine was being salvaged for any useable parts that were left. The left head was broken into at least 3 pieces.
<S>

Not sure what you are finding funny.

One of the most common starting points for a big-block build is the venerable 454 Chevy block. You can still find them and the better ones can handle a huge amount of power. Best of all, they're ripe for the stroker treatment. Take a 454, add a 4.250-inch stroke crank along with some 6.385-inch rods and your displacement shoots up to 489 cubes. Now bore those cylinders out a touch, to say .060-inch over and you end up with the venerable 496. Those extra 42 cubes pay big dividends when it comes to churning out torque, and as a byproduct horsepower.
-
Ah so, am I reading it right that a 4.31 was the largest bore possible for this engine type? Mostly the boat forums have a lot of information about the big ones.
Not sure what you are finding funny.
I do not find it funny I think it's marvellous.

The 427 is the choice for street rods these days. Several of the folks in the Camaro club have 427s with RWHP up to around 2000. Those are all street cars.

I got half a tea cake over said post.

Oh yes I said 'big ones'. Apologies.
