Well I spent a little time today investigating what the doubters have been saying about calibration's and testing of blocks that seem too good to be true, and what I found in the limited area that I was able to physically check my self and found that on the two cylanders at the rear of the block (#7-#8) mechanically checked out to be the same as what the paperwork said it was,, driverside, the paper said .290 and was real close to what my machinist's scale said it was and #7 had the same results,,so I have convinced myself that his calibration was correct and I have two good blocks to work with.

You are truly blest My brother I sent my best 400 block (out of the three I have)to the machine shop and it ended up having a pitting issue in one cylinder that the shop decided to put a sleeve in it without asking me before hand and then proceeded to braze and weld up two places on the deck without informing me of the damage which ended up requiring another sleeve in that block on the other side Maybe it is time for me to make a machine shop change

John, my father said once that a blind squirrel will find a nut once in a while, as far as a lottery ticket, well I do have to go and put gas in the truck here in a little while,,,,

had two blocks one was a 1975 the other is a 1976 both came in with the numbers solidly in the .310-.320 range had a spot here and there that was in the mid 200 range worse being 245, and a couple around .260-.280,,95% are .300 or better. I think I would be questioning the measuring equipment. Chris. Yea Been there done that. I told Bill before hand that what he would get. I think take .100 off them numbers would be closer.

Even if I did reduce the numbers by .100 both block's are good ones.

I think everything has been covered as far as the testing and if it was done correctly then you should have a great block.If you went over all the information with your machinist and are satisfied then get started on the build. The only thing I question is not to use a short fill since your spending a lot of money on the block.The big issue we see is always on the tall fill and block not being clean inside and the cement not sealing against the block and cylinder walls or blocking water passages.But it's your decision as to what gets done. Good luck with your build,and look forward to seeing you at the track.
