As was posted on the other forum, mine has a NA 20 valve motor. It started out as a 7A, but it is much different now. The compression is over 14:1 and it only shares the block and manifold with the 7A now. Once I can post some pictures you'll see what I mean.
I'll break this up into pieces so I can reach 5 posts and hopefully be allowed to post some pictures then. That'll explain quite a bit.
