You are correct. One line from carb supplying vacuum to thermostatic switch and 3 lines running back towards switch and distributor. I think he meant 3 lines only go out from thermo switch. I believe on some 68 cars all 5 ports on the block are used.
7029273 carbs were used in 69 for RA IV 4 speed engines, 7028273 for early 69 RA III 4 speed. 70 455 with RA and 70 RA IV and III 4 speed used 7040273. So date code would indicate what application year Of the date coded 68 carbs i have seen they had the vaccum port on the side of the baseplate. However i have not seen a correct RA II carb to verify if it did. On the engine pic of that car it does not have a vacuum hose in that vicinity but i can't tell if the port is just plugged. I don't think we discussed that but will check my notes. Last edited by Mcronk; 07-26-2020 at 03:25 PM. |

Photos of carb I am currently using. Not correct but it is a real SR carb so that is something. I simplified the vacuum routing so I can get it tuned. The reproduction vacuum hose assembly that fits into the reproduction the switch is loose and let's un-metered air to the engine. I will have to figure out how to remedy that problem
Current set up 72 jets, 42 rods, yellow power piston spring, outer accelerator pump hole, BE secondary rods and 5/8 screw turn tension on the secondary air flap screen. |

Ram Air II progress car #6
I started working on the Ram Air II about a year ago, it is car #6 on the list here. Progress has bee a little slow, but I am also working on the Ram Air I convertible too. I removed the RA II coupe body and have all the bodywork done on it. I also did several sets of doors and decklids for the cars. I am currently working on the two frames and related suspension parts. I have picked out a few of the highlight pictures.

Had one of the best conversations I’ve ever had yesterday.
Tracked down by pure accident thru Facebook, the original owner of my RA2 GTO. I’ll summarizing and keep it short Early 68, he ordered a Hemi Charger as a birthday present to himself as it was supposed to be the best out there. It came in in May 68, but when he went to take possession, the manager refused his 66 Tempest trade in as it had been modified. The gave him a short time to sell it but did not happen. So third week of May, he walked into a little Pontiac dealership in Alliance Ohio to talk to them about what Pontiac had to offer and would they take the trade in. The dealership owner sat him down and showed him literature about this new top HP package that just came available. Prior to that, he never heard of it. He sat down and checked off options on a GTO. About 5 weeks later, he is driving down the road and sees a car transport with a single green 68 GTO. He turns around and follows it to the dealership. He grabs the dealership owner and says we are going for a ride. By third gear, the dealership owner said that is enough and tells him to go back and so they can prep it and install the RA system. He took it back and drove it himself into the service center (it was just 2 bays). He stood there while they installed the system. One side note, he stated the 2nd set of scoops were in the trunk. They were open and already painted Verdoro Green. I asked if he was sure they were open and he said yes, he stood there when they opened the trunk, cut the hood and installed them. And I also found out about the original engine. The RA2 engine broke a valve a few months later and it destroyed everything. They replaced the entire engine under warranty.

No, Orwig motors.
He said it was real small with just enough room for 2 cars in the showroom. It was the owner, his wife and a couple salesman.

That is why I asked him if he was sure. My car had two sets with it when I got it - a closed set and a set that sure looked perfect open. Openings are very straight and clean. The car only had 22K miles on it when I got it. The open scoops were in the hood and the system was in the trunk. The pans could have passed for nos. Now I found out why. After they installed the SR engine he removed the system and installed dual quads on the car. There is much more to the story but he fell on some hard times and the car got repo'd late 1970. The pans were in the trunk at the time and must have always stayed there.
