This is what is in the unit now which is what I had found listed in other postings for the Ram Air III. I'm not attesting to its complete accuracy, but the resulting metering area seemed...

Thanks for the observation on the float pin. I'll correct that condition. The jets, rods and hanger combo in the carb matches the Ram Air III which I though would be a better place to start at with...

Finally had a chance to take in some of Cliff's experienced recommendations and did a careful reassembly of the carb. Three discoveries along the way: 1) wrong base gasket (left side of picture), 2)...

Thanks for the observation. I was afraid of that. I would think the stock tubes would be fine considering the OEM application of the carb for a GSS455 Stage-I should handle my 413 cu in.

Extensive cleaning will begin tonight, but I had already removed the idle mix screws to verify they were the same tip profile and had the same spring lengths. Both were set at 1-1/2 turns open.

My 1970 has an upper close-out. Lower isn't too bad, but you can see how the lower air dam would help push more through the core. Esprit model w/AC originally.

If Cliff happens to scan over this, I'd appreciate his thoughts on the jets and rods chosen for this engine combination which is coupled to a 2800 stall convertor, turbo 350 and 3.23 posi rearend.

I did have it apart to confirm the power piston movement, but now that you mentioned it, the gasket did seem very difficult to un-thread from the metering rods and to get back on. I have a new...

Same with mine. Had a clean-up pass at .005" on the heads and deck. Ross flat tops set at zero, 4.25" stroke with 3.935" bore (350 block .060 over) gave me a 9.3 cr.
