Crab replacement

Carb not crab...dur
Need to get new carb for a 1971 350/270hp, and what is the stock cfm of the qudrajet I have now? Rochester#17054923 0845(know it's not original)

Would this one be fine?

Stock Q-Jet cfm is 750. Why don't you rebuild what you have...? Holley-rebuilt Q-Jets are notorious for a huge amount of problems.

would be very hard to screw it up as bad as what your likely to get from a "Rebuilder" Lars has done a couple detail summaries on rebuilt carbs and found something like 18 problems with a brand new rebuild.
He has a couple good papers on the subject and he can also do the thing for you

send your Qjet to Lars for rebuilding. He does an excellent job and very reasonable pricing!

Quadrajet is easy to rebuild. Get yourself a rebuild kit and just take it slow and methodical. If you don't feel like messing with it, I agree with the others to send it to Lars.
