Hey thanks. Just to clarify:

You think 450 intake manifold will NOT work but could put my fuel distributor and injectors on the 560 manifold, along with my warm up regulator. I'd have to use 560 idle air valve and computer, abandon my aux air valve.

More on that... Only reason I'm looking to use my fuel distributor is because I assume I'd have to use the 560 ECU to run the EHA valve- I'd rather not- and I'd have no provision for cold enrichment. Happy to use 560 fuel distributor if there's some simple way to do enrichment. Any ideas?

A 560 gas pedal with cable- is that what your saying?

On the speedo drive, my 450 drive would fit into the 560 tail housing and have a driven gear off the tailshaft?

WOT- How does the 560 kickdown work? Not an electrical solenoid like 450? I thought 560 had the same switch under the gas pedal?

You've no clue on the exhaust ports- exh manifold compatibility?

Thanks this is a great help! More to come, I'm sure.
