MAF Replacement Options...
So my MAF sensor is toast and while searching for a stock replacment
I came across the Heavy Duty High Flow sensor from Mid America.. its considerably cheaper than the ACDelco and flows better...any reasons why I shouldn't go this route??

If its a Micro-Tech MAF, the calibration tends to run rich under mid-high loads since they tend to over estimate the airflow.
These are also quite sensitive to ambient air temperature. Richer when cold, and leaner when hot.
I wouldn't recommend one unless you're really on top of the tune.
Another option, especially for the tuner crowd would be a Ford MAF conversion. This takes a little bit of work and of course, a custom tune, but in the long run it should pay off, due to the availability of cheap Ford sensors. With this approach it is also possible to extend the range for higher HP applications.
I'm running an 05+ Ford slot style maf in a 3" tube with an extended range tune. My total cost was $130 including a used 05 Mustang MAF, VMP MAF flange and Ford pigtail. My tuning is still in the works, but is progressing satisfactorily.
For a stock type replacement, you could use an inexpensive 3" draw through MAF housing instead of the flange and tube arrangement. I could use a guinea pig, to work out a stock like tune. Hey Agent86, think about how nice a yellow powdercoated 3" MAF housing would look on your car.
Of course, the necessary tuning takes some know-how and would also add some cost, but it can be done.

I know of no reason what-so-ever to go with anything other than stock.
Even if you find a higher flowing MAF, it's unlikely that your stock MAF is an intake restrictor......so your gains will be......negligable.
IMHO of course.

alright well it looks like everyone agrees.. acdelco it is.. i will definatley be calling around for the best price. napa is on the list , i usually buy from them for my other vehicles repairs and they seem to be able to cut deals a bit..
im glad someone commented on the flow aspect.. although it looks like ill be picking up a 400block soon so im trying to make all my part purchases with that engine build in mind.. i didnt think the stock maf was a restrictive part of the intake and hopefully it wont be later on down the road with the 420 incher.

Ummm, I didn't check the P/N on my IROC MAF vs the old one on the Vette but the flow rates (as seen on my scan tool) at various engine speeds looked to be the same.
I believe that '86-'89 Camaro & Firebird MAFs will work on that range year Vettes. Certainly a bone yard MAF from a donor F-body would be a rather cheap (compared with a new MAF) test unit.
