Tunnel ram, linkage and cable question.

Cope said

Still gotta decide on the TC. (stock converter still) My engine builder says 2,800 but I'm leaning more towards 3,500 as I wanna be pulling as much vacuum as I can before launch and may re cam this winter.

Also how the hell do you tune a plate style carb? I've always had 4150s. do you buy new plates or what? Just tune the primaries?

What about fuel pressure? Now that I'm feeding four bowls vs two, should I up my pressure? I was running 5 1/2-6 PSI. should i bump that up?

You have to find out which plates you have, and then by the correct plate. It's been decades since I did a 4160 so I don't remember the particulars, but in the catalog or one of the Holley books you can find all the plates they offer and figure out what you need.

And yes, a 2800 converter is about stock. I'd call PTC or someone like that and tell them what you have and let them pick it. FWIW I know guys running 5000 and 5500 converters on the street with no issues.

It's hard to get the converter too loose, within reason. A converter that is too tight will screw you hard.
