Barry;  The intake manifold is an Atkins wrap over, it appears to be for a
race car application as the carb leans about 4 degrees to the front of the
engine.  It looks like I will have to saw it in two and reweld it, to level
the carb with the engine.  Don't you just have to love this experimenting
where every thing appears to need changing.  Keeps the adrenalin rushing
though.  JohnD
