Been there and done that!
1. No problem there.
2. Have cam reground to specs that will fit what you want from the engine.
(Delta Cam)
3. This is where the problem arises. If pistons need changed good luck in
finding oversized pistons that will work on the early rods otherwise you
will need to change all over to 3000 rods and pistons. I would also
recommend no more than a .040 bore on the early engine.
4. If I had to do it over again I would just find a later 3000 engine to
rebuild. Mine has been running strong going on 10 years and the only reason
I used the older engine was because it was original to the car.

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
