What's the dish volume/approx compression ratio on these?

 

[turbonut85]

What's the compression ratio with these on stock stroke?

 

[wickedtt]

Bore 4.000
Comp Height 1.850
Pin Dia. .940
Dish -.245
The compression Ratio was going to be around 8:5 to 9:1



I have a 4.1 block also but I oiled it up bagged it and put it in storage. I don't feel like degreasing it just for pics lol.. its the '291' block. It's the one beefier in the deck area

The close up of the ring boxes says they're for a 4.005" bore?

That is a huge amount of piston dish. Are you sure its 8.5:1 to 9.0:1?

Those are file fit rings .005 over for a 4" bore.

The specs I listed on the pistons and rings are what is listed JE on the boxes. As far as the compression ratio I was shooting for 9:1 myself. I'm no engine builder but I know alot of things can change your compression when biuding a motor.

With a 9.535" deck height,4.020" diameter .060" thick head gaskets,5.970" long connecting rods,24.5 cc piston dish,and 46 cc combustion chambers,these pistons will have a static compression ratio of 9.02 to 1.
256 cu. in.

I'm unclear on the c.r.? Is the dish -24.5 or -.245??? It makes a big difference in the static c.r.

You can tell by the pictures that it can't be .245.
