We did calculate for head gaskets. And when all measurements were taken, we both manually calculated and entered them into the auto calculators, they were never more than .1 different. And we did vary the angle to make sure there were no air pockets. CC'ing is as per raced. We cleaned the top of the block and head surface to insure a good fit on plate. That's all.

These measurements were all done by a 30 plus year engine builder who has been called on by SCCA in the past. I'll go to the bank with him. Everyone involved watched him and were satisfied including engine builders.

As I clearly said, I did not have the staff at Sonoma to whistle the cars along with a couple of another factors including having HP & FP together each day. That will not be the case at VIR in 2019. The whistler will be there!

I've got some more things to check, but as I said before, I do believe we found a problem with the whistler on domed or pistons that protrude from the block. Once I figure this out, I will try to establish a guide line. For now, be prepared to be checked at VIR.

And BTW, rods are not free. Yes, you can use rods of different material, but they must be the same length. We did pull rods before to check length and will do it again.

Hope this helps you get ready for VIR.

I'm safe. Will not be anywhere NEAR fast enough to be on the podium.

What? Not on the podium? Heck, maybe at VIR I should do like our short track series does and have a random draw outside the top three for a full post race tech. You guys like that idea? :D

P. S. Just kidding.

Yeah I remember watching Buddy Arrington draw that card at Martinsville speedway years ago and watching the crew packing the cylinders with ice after finishing like 20th or something trying to get through Tech.

Jim, we also need to know what fluid you will be using - even that makes a difference. I am still baffled by how the complete assembly can be accurately cc'd when bubbles are hard to remove even when you can see them. One method that I use when checking piston dome volume is to move the piston down a specified amount in the cylinder and calculate the difference if a specified volume plate is not available.

They did a superb job of cc'ing and they used isopropyl alcohol for the fluid. Sam Neave did the hands on work and everything was done perfectly. Nice job guys :applause:

Actually, I was going to recruit you to handle the rotary motors. Was on my way to your shop today to let you know. Get that finger ready!

Still don't understand how those things work. Cubic inches or cubic leagues?

Sam that is exactly how they did it.
