So since I installed the 403, my Qjet was very lean at idle and part throttle. I am shocked it actually idled and drove so well. No bogs or hick ups at all. I went maybe a 1/4 turn on the idle mixture screws and one turn out on the APT. Much better no longer 15 to 16 at idle and no more 16 to 17 part throttle. Now 14's at idle and maybe 15 at part throttle. The full throttle AFR is still 11 to 11.5 even with the leaner AY secondary rods from the CV rods. I currently have a G hanger on there. I may try my V hanger, which should lean it out considerably. I will test😁 and report back.

Actually the leanest hanger I have is a P. With the leaner AY rods and the P hanger, very high 11's to 12.28 full throttle AFR. Perfect.

My Wife's eyes were bugging her so she didn't want to go fishing on our local Reservoir😱. So I finally installed the Inline Tube direct replacement throttle cable. It fit as stock. I liked the aftermarket locking clip, so I used it over their hair pin clip. I also didn't use the rubber grommet and center tube. The cable sits on the large in piece on this 78 403 800 cfm Qjet. I added two extra washers on top of the one included, so it can't slip off the larger portion closer the linkage edge.

This arrived. It looks really well made. I like the idea of a pan mounted dipstick. Canton having that option is just another reason to run one.

How do you like the Canton pan Christian? Have any pictures of it, does it have an internal windage tray like the Moroso? I have the Moroso pan on my 455 and while it’s ok, I’m always on the lookout for better alternatives.

It is baffled and has a swinging side baffle. It is a better pan than the Milidon or Moroso. Both of those have had leak issues turning into huge cracks in some cases.
