71 RR 340 Six Barrel Conversion W/Air Grabber

I would appreciate information on weather or not I would have any clearance issues if I replaced the stock 4 barrel intake with a stock 340 six barrel setup ? Is this doable with an Air Grabber hood? Would I experience any fitment issues with my air grabber air box sealing to the six barrel air cleaner ? Thanks for any information that anyone can offer.

No issues...


I have a Pack on a 72 RR with a Grabber.

Thanks for the feedback. I feel better now about moving forward with the project.

Yes you can get in trouble. The air cleaner base on a 340-440 are the same 2" high. The base on a 383-400 are 2 1/2 high. If you use the 2 1/2 it will break the bubble!!!

I would agree that he should check the air cleaner base height, but he talking about a 340 Six Barrel conversion.

The factory never made a 383-400 Six Barrel air cleaner base plate so the different height of a low deck big block base plate isn't a problem in his case.

Thanks for all the good comments. Just to clarify in my own mind, If I use a 440 six barrel air cleaner on my 340 six barrel set-up, it will work on a 71 RR Air Grabber hood ??

Thanks for all the help.

Yes as I said 440 and 340 are the same.

340 six pack with a 440 six pack air cleaner in a 71-2 B Body = Nothing Broken

Great News. THANKS .......

Thanks........

Sorry for any mixup. The single carb air cleaners are the ones that are different the six pack are the same!

No problem at all. I was a little lost in this case as I have never been involved with a small block six barrel set-up going in an air grabber car. Thanks for all the help !!
