Boreing 400 etc

[Gen1Pat]

Nope. Don't have a 12:1 to go by. All I would need is the height measurement. Using that crank with the 400 cylinder, you'd have to come up with a way to make up 3mm difference. That's only .120". Now... if 357 had an .080" spacer made, and is running without base gaskets, I can only assume he went for zero deck height. If that's the case, then the 12:1 is around .080" taller than stock (idk what the deck height is for a 366). So there is 2mm down, 1 to go. The average base gasket thickness is .020". Take that out and I'd have .020" deck height, all this is hypothetical because I don't have any/all the measurements I need. Atleast nowing the stock and 12:1 deck heights would help me figure out the piston height differnce.

You lost me at the .080 spacer, and zero deck height.. lol

I think it would be a bit taller than that, but we'll never know till it's been measured?

 

['00 WO-YA!]

well finally got my motor back together i have the 4mm stroker crank and went and had a jug spacer made to 80 thousandths with no gaskets blue silicone and bought the 85mm je piston 12:1 comp with cometic head gasket and it runs nice

I'd like to know a lil more about this. How'd the timing chain work out? Wish we had pics of it going together. Who made up the spacer for ya?

 

[357warrior]

The original timing chain works just fine no complications. The spacer I got made at dick rughs in uniontown and just had himm trace and cut out a base gasket out of aluminum.

So what did your deck height turn out to be at? How far down from the top of the cylinder was your piston at TDC? I have a 10.5:1 stroker piston, but 388 is what I'd really like to get.

 

[357warrior]

Its just about dead even its super close

 

[Gen1Pat]

So is your cr 12:1 still?

 

[357warrior]

I would say i might be 1 or 2 thousandths off but eigrher way that is still close
