3 deuces...Rochester or Demon...which?

sbc...which is the better setup...why?

 

Be prepared to spend some money with the Demons...

 

Rochesters have been around forever and parts are available everywhere. Books have been written on every possible way to tune them, and they are certainly traditional. A good 3X2 setup can be had for around $500 used and ready to run.

 

The demon setup is about the same and any of the others. I hear they are fickle though.

 

Better look around, if you haven't priced one lately, the average is $1200 ranging upwards to $2400.

 

up canada way 3 duces will cost you $2500 clams or so ,not including filters
(k&n), each 2 jet rochester costs $140.00 (napa).
i scratch built the fuel lines. then you pretty much have to buy a kit to properly block off the idle circuits on the front and back carbs(speedway),
jetting,metering rods and accelerator pump springs are also changed.
demon carbs look cool but depending where you purchase them can cost more than twice the cost per carb!
that being said nothing short of a supercharger beats the cool factor or the blood rush of 3 duces at wot!

 

www.hotrodcarbs.com has a set that will cost around $2500. You may be able to piece together a set yourself but finding the correct carbs is a pain, plus you have to buy a kit to adapt the system to work as a true tri power (power valve blockoffs, correct throttle blades, etc...). Speedway has a kit or hotrodcarbs. I had to cannibalize several carbs to get a matching set.

Barry Grant had the six shooter which ran over $3K. The set up never worked very well. Barry Grant stood by his system and rebuilt the carbs, however, it ran great for a couple of months and now it's a garage ornament.

 

ive had tripowers for years my first one was a fenten with rochester carbs , bullitproof and very econimical to run old ariganal 58 tripowers , the new ones (demons ), you have to reach way down low in your pockets to get , hellmit would make look like im trying to go play tennis or something

 

I sold a nice e/brock trips setup complete (no a/clnrs) with linkage and t/stat housing for $2750. that was just about a year ago, so the $500 estimate is a bit low for a fully workable/tunable bolt-on unit. I have no experience with the Demons...they are probably fine, but not 'traditional' really. 2GCs are a known product, when set up properly for multi-carb use, then they're hard to beat for looks and performance. We (the royal WE) ran 94s and 97s back 'in the day', and fought leaks and other anomalies (not the least of which was our inexperience). When GM came out with factory 3x2s, and carbs became available - we dropped the Strombergs and Chandler-Groves like a wet prophylactic.
