John,
I had a 2639cc block bored out to a 3000 block (2912cc) by a local machine
shop. The machinist had to push out and re sleeve two of the cylinders as
they had a dark stain or casting mark on them. So, this was done just to be
on the safe side. My machinist indicated that there was plenty of metal
left on the cylinder walls for general use. I have yet to start the engine
to inform you of the success.

Ladies and Gentlemen,
Need some technical information. I have purchased a
1957 BN4 Longbridge 100 6 with the 2 port head. I have the head and
manifolds from a 3000 that I want to transplant.
1) Will the rocker assembly transfer
to the new head?
2) Do I need to get a different cam to account for the new valves?
3) Can I overbore this block to 2912cc without issue?
4) What else
do I need to know to make this work?
Thanks
