Mac.. Yes I had the auto kickdown connected when I had it on the 289.
And yes it has the original jets back in it now. I bought a 750 demon and put the larger jets I had in the 650 in that.
The 650 is running 75 primary and 83 secondary jets now.
This is how I ran it on the 289.
The 289 had dart Heads, small solid flat tappet cam, performer manifold, extractors. It ran a 13.3 1/4 mile and was perfectly streetable.
Cheers Ron
