Rochester Quadrajet - 7040270
Has anyone used a reproduction carb? I need a carb as the original was gone when I bought the car, not going to be a show car but would like it to be as stock as possible. I dont want to buy an original on ebay as I dont know much about these carbs and dont wanna pay $2000 for a reproduction that I can get for $400. The guy selling the reproduction said they look and work as good, if not better then the original, and can stamp them with the numbers I want.
thanks. |

If someone can provide me with the correct casting and stamped numbers of a 7040270 in a PM, I'll let you know of one for half of that $2000. I bought one for my Judge when I owned it as it had the exact date stamp of the Judges' original one.

Let me correct my first post: I don't wanna pay $2000 for an original and later find out it is a reproduction that I can buy for $400. I don't care if it is date correct. I just want a working ram air carb for my car. And if I can't find an original for a reasonable price and if the reproductions work as good as the original and look close enough I might go that route. Until I feel the need for a original numbers matching date correct carb.

You can have a Q-jet calibrated to the 270(ram air) specs without the restamping....

I have never seen a correctly "reproduced" RamAir Q-jet.
In fact itīs very hard if not impossible to copy a 1969-70 RamAir Q-jet throttle plate and air horn. To replace a 1970 RA carb my first choice would be a 1973-74 Pontiac unit, modify the idle circuit accordingly to suit the engine, then tune the main and WOT for best performance. Also, these units have provision for an electric choke. 1969-74 Buick Q-jets are also nice if you have to have the divorced choke. |

What about the SR 270 carbs? Date won't be correct, but they are RA spec'd carbs??

The SR 270 carbs and all SR carbs are manufactured by Delco/Rochester and are correct in every respect.
This is NOT the case with epay carbbutchers "manufactured" RamAir Q-jets. |

I got taken on epay over a 270 carb for my Judge, wish i had paid 400 for it. Turned out to be a fairly well done copy, still was pissed that i spent over 1K for it. i still have been in the hunt for one of these dated in the sept oct early Nov date range. Not sure how the fakes run but I may end up finding out if i don't find a real one at least for the short term and I can let everyone know. mark
