340 manifolds and Magnum heads

Yep, drivers side the same way. I used some 16 gauge steel and made some adapters to fix it. It just took some time to fit them.
I also had an issue with alternator. I am using a square back late 70's alternator and it hit the freeze plug boss. I had some leftover alternator spacers from a van and cut them down to line everything up.
The left side manifold hit the heads deck where the head bolts are. A little grinding took care of that.
