Some "Dynomite" Heads! - Page 10 - ZR-1 Net Registry Forums

Well I just couldn't leave it alone. Found this glass burette kit complete with stand and teflon stopcock for $60 shipped and just had to have it. It has a 50cc capacity with .1cc markings which greatly increases the accuracy of my measurements. I remeasured using the burette and was pleasantly surprised by how accurate my previous measurements were using the syringe method - all chambers were within about .25cc of my prior measurements. As it stands now I have 1 chamber at 42.5cc, 4 at 42.4cc, 1 at 42.3cc, 1 at 42cc and 1 at 41.8cc. I'm happy with the 5 chambers that are within a .1cc so I just have 3 that require some minor material removal. I am still using water at this time, if I can verify that my set-up is alcohol compatible then I will probably give that a try next since it's supposed to be a better measuring liquid. One thing I learned right away is that cleanliness is critical to using a burette, it doesn't take much debris to create a clog and it's a real bitch to get it out.

P.S. This anal retentive madness is all your fault Cliff since you won't be picking up your stuff for a little while yet

If you have an IH ported, can you CC that to compare to my siamese job?

Sure, did you want to see my 368 "B" port partial siamese or a conventional 2 port 36mm? What did you use to seal the injector hole?

LGAFF · 04-22-2011

I sealed with an injector, would be neat to see both, but I was thinking of the 36mm port. Mine ended up about 235CC

Hey Rob

I know these have crazy hours in them. Have you come up with a price for porting the heads yet?

Polo-1 · 04-22-2011

I thought test set was free
