Yes, I work for CS Performance and we do all cylinder boring in house. We are using the same boring bar for the cylinder cast and the counter bore. I bought a different bit to counter sink it. The cases were bored out at my fathers shop, also where we will deck the cylinder. He is doing all the machining, helping me insall the sleeves and I am doing the rest.

Nice :biggthumpup:

What are you doing for porting for the flat tops?

 

[BROSS]

Sending them to Tim Judge.:sneaky:

 

[Matt_E]

Excellent! You'll be a happy camper.

Some may say he's all about racing, but I have seen alot of his work, talked to him, felt his engins and nothing else compares to me. IMO

See thats what puts a smile on my face, I CAN'T WAIT.

Well the cylinders are bored and man thats thin but oh well, installing the sleeves next.

 

[BROSS]

Well sence I didn't do a build thread the first time I did the ski here are some pics to tide you over.:drillsergeant:

 

[BROSS]

The cylinders are ready for decking, that was so easy droping the sleeves, also have to rough bore the cylinder before it goes out.

 

[BROSS]

Started the grinding yesterday, and getting close on one side.

Yea, I wasn't shure to do it after I started grinding or before, so I started grinding and thats how far I got. I will get it close and prob put the epoxy in the runner and smooth it all out from there.:icon16:

 

[teton]

i thought the humps were good for low end, dont know where i read it though.....this would be good to know as im about to do a similar build

 

[BROSS]

I never heard what those were for, I'm just going by the cases I've seen done by Tim Judge, I think they call it updraft porting. Also gonna use a angled reed spacer. Here are the cylinders decked, ready for rough bore.

 

[BROSS]

Opps
