Steve,
In my original copy, in the paragraph above what you quoted, talking
about
head gaskets, states: "This is true if you have a 260 cylinder block, but most
of the Tigers are coming through with what is actually a 289 block only bored
to 260"s 3.80 bore!"
My understanding of the page was that the 3 freeze plug block was bored
to 3.80" and that it could be bored to 4.0". However I recommend that any one
considering boring a Tiger 3 freeze plug block from 3.80 to 4.0 should do a
sonic check to see if there is enough wall thickness before the block is bored.
Any way, why waste a Tiger Block, when 289's and 302's are so available
from the junk yards or the rebuilders? The 5 versis 6 bolt is the only hassle.
I have found this book to be of help to me many times. It is the best
book on Tigers I have found. Now if we could just get the mechcanics to go by
the Flat Rate Table in the book.
