This response explains why we had so many problems that we gave
up on our swap. We figured that rather than re-invent the wheel,
we'd wait 'till someone told us what the answers were.

We were going the opposite way: the original "A" 3 syncro transmission
grenaded, and we had a 1500 zero time rebuild waiting to go back in.
The cost of rebuilding the 3 syncro was prohibitive, and we just
happened to have a good 4 syncro od transmission in a parts car.

Ok, we'll do that before we install the 1800.

Hmm; David Vizard notes in his book on the BMC "A" series engine
(small block ala minis, sprites, midgets) that the cast iron
manifold was actually pretty good. Does anyone know if the "B"
series (big block) received as good a design??
