Some shorts of the whys...
For the most part, Biggest Piston Possible=Biggest Intake Valve Possible=Biggest HP Possible. Siamese walls are the only way to get the biggest piston. That's why the Butler Aluminum block isn't the first choice for every race engine(sleeves need to sit on something and end up being a deck surface for the head gasket too). The thinnest you can go with siamese cylinders is pretty much .180" and that's not much sealing surface between cylinders...but you do get a nice diameter piston and ability to play with the heads a bunch. The other thing with large bores and the "caliper" picture, stock placement of water holes get real dam close to bores when opening up to max diameter. Yea, some think that I'm a shill for KRE or something, but I'm not stupid Tom, that block is a coffee table if the material can't stand up to the abuse. -Rob WWW.ICTCengines.com Dammen meant "NO" water in between cylinders |

You being a "Kauffman Man" according to some and me being a "Butler Man" according to others, we ought to just sit down together and have a beer sometime and discuss real engineering practices and how it should be done. Agree? Siamese walls tie the cylinders together in the middle of the block. NO water between the two cylinders. The 400 small block chevy was one of the first GM engines to do it so that they could get a 4.12 bore in the small block case length. Tom V.

I think we should all sit down, have a beer, and talk about women.

Amen, brother! Come to Norwalk Dil and we can try and make it happen. Steve, I hate to say this but that was some expensive tuition for that class.

I think we are stuck at 39K and may not cross over to 40K "looks" 732 posts now.
The calm before the S*** really hits the fan! Tom V.

Ponjohn, until you have been in combat, you really can't appreciate what a fine SH*t storm really looks like. Actually I think this is really a pretty mild deal. Kind of like a high school argument between a couple of kids, a lot of words, no real punches thrown. TALK.
That is all my comment meant. Tom V.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
