Quick and Dirty Rebuild of the 565 - Thanks Lem

Happy Easter...



The first pull with the TR was run 18. Steve pulled it from 4,800 - 6,000 to check the set up. It was all over the place, but mostly lean. I think the biggest jet change we put in for the first set-up was 7 sizes.

Made run 19 and the pk trq was 763 at 5,900 pk hp 949 @ 7,400.

Made changes jet and air bleeds in runs run 20, 21,22.

Run 23 we ended up with: ( keep in mind the primary side 1-4 has a PV )
1: 87
2: 81
3: 79
4: 82
5: 97
6: 91
7: 104
8: 97

Cly to Cly AF:


We will be making mods to the plenum that will enhance the signal to the boosters and cly to cly distribution. We'll  also have several carb spacer choices to try on the dyno.

I meant to ask this ... ...  Spark Plugs

I've run the Autolite 51's for years and was having a hard time locating them locally a few days before dyno day. My local Ford connection told me to switch over to the  NGK  R5671A-9.  So that's what we ran on the dyno.


I'm think for running in the boat and all the recreation running it does I might go to the  -8  plug.

-8 on the water would be fine.

Since your T/R plenum mod thread I’ve been meaning to call and make a suggestion on that as well, in the area of runners.  I imagine there’s still more potential in that casting & further mods relative to your combo.

Thoughts
Dyno tested with Hooker 2.25" x 28" L  with 17" x 4" collector.

I pulled an old set of Hooker headers out of the shed:  2.25" x 26" L x 12" x 4" collector.


What do you think the short header would do on the dyno compared to the set already tested ? :



Give them a shot when we go back, or just leave them at home ?

A header change is a quick change. I would certainly do a comparison.

Cheers

A few new parts:

I doubt you’ll see any difference

Not for this rebuild, but some new stuff:
