Help!

I bought a block that came from jasper it has 030 on the deck does the mean it's been decked? And i bought .010 shorter piston if I get thicker head gaskets to make up the difference??

That could also mean cylinder bore.

I would call them to confirm. Only way to be sure.

 

[jtlane]

All my pistons come out the top of the deck .
.021 is that bad? And it means it's been bored got a hold of the thank you bud

 

[jtlane]

Anyone?

Crazy idea but ......Why don't you measure the bore ?

 

[jtlane]

I did just wasn't sure about the deck does anybody know the tolerances

 

[jtlane]

Does anybody know the Piston deck Torrance

I'd love to help but I don't know. Have you checked their website? If you don't get an answer by Monday, and if I remember, I could go next door and ask them, I have a Jasper distributor next to me

I got a .066 thick cometic head gaskets if that helps.

 

[jtlane]

I have .01 shorter pistons just wondering what the deck high tolerance was and how does your head gaskets hold up

From my factory service manuals, this is the only spec I could find:

Piston Height Above Crankcase: 0.254-0.787 mm (0.010-0.031 in)

I'm assuming that "above crankcase" means above the block deck. Cheers!
