Re: 20 years later
More bad news:
The heads came off tonight and the #8 hole was not only sezed up tight but even had dirt on top of the piston. The inside of the head on that hole had rust scale that had fallen down on top of the piston. The ex valve had been ope all those years and the heat and cooling cycles had moved air in and out. The block will need to be bored out to clean it up but shold not be a problem.
The other bad thing was one of the heads is not from this motor. It has a different casting number and when looked up it has a bigger combustion chamber by 2.1cc. That is if it was not properly matched when it was put on and I won't know that until I get the heads reworked.
The motor was also to have a solid lifter cam in it, but nope a hyd cam was in it instead. I don't know the specs on that cam yet.
In the end I will have a fine running 427 that is for sure but not an all original motor as I had hoped it would be.

I was told this Project had a L-72 427 425HP, It did not.
It does have a 427 block and parts from various 427 motors. It will end up with a nice strong 454 in the end.
It has not been run for 20+ years
