Rochester 2 Jet

JMO, the 2G and 2GC are very underrated and underutilized. If you have a jet kit, that is a plus. Probably best utilized with an Offy C and a 2V X 4V adapter or have the stock intake machined and fitted with a base/carb mount. That is a common modification done by SB6 owners and info can be found here: FORDSIX PERFORMANCE - View forum - 144-250 "Small Block" Six Performance

I agree with Harte3. Next to the Autolite 2100/2150 it is probably the most overlooked option for a performance upgrade, and it has a smaller bolt pattern than the Holley / Autolite which can be an advantage for some tight packaging situations.
While I don't have one on a 300 I do have one on a 302 (disguised as a tri-power with two dummy carbs on each side) and that little baby fairly squirts from stoplite-to-stoplite.

Yup. I mounted them on a Mustang GT engine (w/ toploader and 4.11 posi) and had to turn them around backwards to clear the distributor at the front of the Ford.
When my wife wasn't driving this to work I used to take it in to DEARBORN to work. Sometimes I would take it out at lunch time and I had to drive by the front of the EEE building where all the execs had their luxo sedans parked.
Look at the exhaust system. When I hammered that baby as I passed by all those big Lincolns, Jags, and Expeditions it set off all those car alarms. What a concert!
Good. Clean. Fun.

Thanks for the responses guys. My main thing for me now days is efficiency. In 76 I got my first rig, a 68 toyota landcruiser I made an adapter for an old 2 jet I found in my dads junk stash. I used a short piece of, I think 2 1/2" exhaust pipe that I ovaled, and a couple 1/4 plates crudely hacked out with a torch. It ran great (not counting real cold start ups) had a lot more power and used a lot more gas. I was 17 and my foot was rather heavy then, but gas was cheap. After graduation I acquired a 69 Landcruiser which had a manifold that looked almost exactly like an Offy. On that I tried a little Holly, a old Carter, didn't like those and finally went with an Autolite 2100. Lots of jet testing and best I got was 20MPG, average about 18. Never messed with the carb again in 25 years and a little over 300,000 miles. The Autolite was the only carb that didn't flood out on super steep hills. The reason for the thread is I read somewhere that the 2 Jet was the most efficient two barrel ever made. Somewhere online I found pics of a 300 in an old Ford chassis motorhome, with what looked like a factory (or coach ) mounted 2 Jet.
