Is there a size difference between lt1 camaro MAFs and lt1 caprice/whatever mafs?

The maf I have which is stock (not sure what lt1 car it came from) measures from end to end about 3 1/4 inches, but everything I see on ebay says 3 inch or 3 1/2 inch, so I'm not sure where these guys are getting the measurements from (I'm measuring the opening).

So what size IS a stock MAF for an lt1 camaro?

 

B-body MAFs are slightly smaller in diameter than an F-body.

 

LT1 camaro has a 3.5" outside diameter. Caprices I believe are 3".

 

But measuring from where??

The opening isn't either of those.. the larger part that has the barcode and stuff on it, that's 3.5inches.

So do i have a camaro maf?

 

Any difference between the stock MAF for an LT1 F-Body, and an LT1 Vette? Or LT4 Vette? I know aftermarket MAF's are a pin to accomodate for in tuning, but I was just wondering about those ones ...

 

Here...

This one is from my camaro. 7.5 - 4 = 3.5"

 

That's with stock MAF ends?

 

Yes, it is from a stock camaro. It is ported but that has nothing to do with it. All camaro and firebirds got this size MAF sensor (3.5"). Carpices and B-bodies got smaller MAFs like shoebox said.

 

What about Vette's and LT4's ?

 

I tried to fit a spare ported MAF I had out of one of my lt1's into a buddys 95 Impalla SS. As the previous posts have stated, they don't match up.

 

Yea, I know the impala's are more restictive, but I thought the Vette LT1s made their extra power from true duals and a less restictive intake. So are they the same deal as a camaro for the MAF? And what about the Grand Sports ? and LT4 F-bodies?

Aftermarket MAF's are a waste of money, and for proper tuning you pretty much need the screen and a stock style MAF, be it LT1 or LS1. Aftermarket ones suck to tune for.

 

Time to wake up the dead thread...

Are these F-Body or B-body MAF's? They appear to be pretty similar.
