I purchased a complete running 4bolt 350.
I yanked the heads and pan off.
I saw flat tops with 4 valve reliefs and a small circle in the middle of them.They also have arrows facing forward.I think they are either stock pistops or cheap rebuilders.

I saw the part number on the skirt.It looked like either 8557 or B557.

Anyone know what it is and what the "Advertised" compression is with 67cc heads?

I brought the thing to top dead center and layed a feeler gauge on the piston and roughly figured the deck height at .055.
I'm probably going to run a Fel-Pro .015 shim gasket.

I believe you are right. Sounds like a stock .020 destroked Badger 557

:eek: Destroked pistons???

What the graemlins/angry.gif is that?

That's what the rebuilder pistons that have the pin moved .020 are called

So they lose a little cubes AND compression :confused:

No, this is just how they are described in the catalogs.
I don't have a clue why I guess it was someones idea of an easy way to tell you the pin was moved without simply saying the pin is moved up .020.
It is a 350 piston with the pin moved up just as they do in "stroker pistons" only some bright spark in advertising or what ever decided to give them a 'cute" name?
Why are we even discussing this, it's a piston with horrible quench with a stupid name designed to be put in a block that may have been decked. :D

:( yea I know and ouch :(

I was planning on running this engine a little.
My friend told me it was a 350 4bolt with flat top's.

I thought I could find what the piston is ( :( ) and compute the compression and slap an appropriate stick in it.

I have looked online for this piston but I can't find any info.

I know this hurts (it hurts me more than you because I now own the damn thing :( ) but
could you help me figure what the compression might be? :confused:

Hey, all is not lost :D
You can get it to a smokin 8.4 with a .015 1094 felpro & 76cc heads or better, 9.5 with some 64cc vortecs ;)
This is assuming they are really .055 down which is .010 further than they should be unless the rods got "destroked" .010 when they were done too

======EDIT============
9.2 with 67cc's

Someone just shoot me graemlins/clonk.gif :(

Gee I might get away with sticking an RV cam in it graemlins/sad.gif graemlins/boring.gif

Just a thought do you know of a cam that would work well with 9,2:1

World S/R Torkers 202/160 very mild bowl port,1 5/8 headers,RPM Manifold,

3.42's, th-350,2400 stall,and 3400 pounds???

May have to get me one of those Comp XE grinds.
Humm maby the
XE262H- 262 270 218 224 462 469 110

Uh... Well...Someone did shoot me.

I rechecked the deck height after cleaning off some carbon and gasket material on the block and heads.

The result... .060 :eek: WTF!!!

It looks like the Fel-Pro .015 will bring my quench to a real sweet .075 tongue.gif

It looks like I bought a rebuilder 350 4bolt with crank,rods,water pump,pulleys, and valve covers.

But hey at least it's a 4bolt with high nickel and high tin, it's also standard bore.

Don't feel bad. The engine in my truck has 9.4-1 with vortec heads, .040 deck height, and .038 head gaskets. Yeah, thats right...078 deck height :eek: :rolleyes: But, I built the shortblock back before I knew much about quench. I use an XE268 (which would work great in your application BTW). I get 180psi cranking compression, run on 89 octane (87 in a pinch), and can burn the tires off of it from a 15mph roll with 3.08 gears and a 2000 stall convertor. It's not perfect, but it gets the job done.
