Greg,
Always great to see the TQs get a good wrap. The most underrated 4 bbl carb of all time. I first started using them in the late 70s. I have two 850 Comp Series & a mate has an 850 & a 1000. When I put a Ford TQ on my 440 Dodge & went for a drive, the engine almost stopped when the secondaries came in. I went home & increased the sec MJ & AB to the same size as a Mopar TQ I had, & presto, problem fixed. Any idea why the Ford TQs used such small sec jets, some the sec jets were smaller than the pri! The only downside is that the Idle Down channel is a pain to enlarge.

The spray bar nozzle concept in post 21 has been around for a while. CB Performance in the US was offering it over 20 yrs ago for 40 & 44 mm Weber & Dellorto carbs. May have been others before them.
