old school tunnel ram and carbs question

[musclcar]

okay finally i'm going to put the tunnel ram on this weekend !!.one question though ?? is what is a good baseline carb set-up [i.e] jets,power valves and pump cams for these 600 vac secondary carbs.right now on my motor i'm running a very nicely tuned holley 750 DP,it has these parts in it rimary - #76 jets, #8.5 power valve, #31 squirter and orange pump camsecondary - #80 jets ,#35 squirter and red pump camso what size jets will work i know the power valve will stay at 8.5 and the pump cams orange "maybe"

How did you make out this weekend working on the tunnel ram? Jets stay the same size. Remove choke and choke plates on each carburetor (if it backfires they will flip 180 degrees).

well i went to a #64 jet,#31 squirters,white pump cams,a #9 secondary plate and it seems to work good.there is no choke plate in either carb since i live in sunny so. california.i might try a 50cc reo pump though and see what it'll do because of the large plenum and long runners to the intake valves.also my dual carb linkage is set up right now for both to open at the same time instead of progressive.again this combo seems to be working quite well and feels really responsive when i hit the loud pedal.my friend did a really nice job in restoring the intake and zinc chromating the carbs

Hey everyone, wanted to start with saying this has been a really helpful string. Im a younger guy, bought a chevelle when i was 17 and now just deciding its time to dump some cash into it. Kicking around my friends garage is a rectangle port tunnel ram, i like the look of tunnel rams, but i have oval port heads. i read somewhere recently that you can use the rectangle port intake with matching gaskets on oval port heads.. any ideas or comments here guys?

You can run square port intakes on oval port heads, I've seen it done with success, but it is certainly not the "optimal" situation. Square port intakes are designed for square port heads, and are typically higher rise and often times of open plenum (single plane) design. These high rise and/or single plane intakes are a poor match not only in port type but overall design for the smaller, less flowing oval port heads. I'd say you can get away with it if it's a dual plane fairly low-rise square port intake going on oval port heads, but if it's a high rise single plane or something really high rise like a tunnel ram I'd say forget it. It'll give you more headaches and rob you of more power than the "cool looks" will ever reward you with. Just my opinion, I'm sure others will chime in.
