Im putting together a 302 for a friend. I sent him to the local speed shop to order parts ,I had told him to order a 75mm mass airflow meter calibrated for 24lb injectors. I thought we were getting a granatelli motorsports maf meter but apparently the guy at the shop said he could save my friend a couple of bucks by getting the c&l meter. Well the parts showed up and what we recieved was a 73mm maf meter. It says in the instructions that you are to use the factory sensor and swap it on to the c&l meter. Is this the way it works. How is this suposed to be calibrated for 24lb injectors when you are using the stock sensor thats just going into a bigger housing. Plus i was told from another source that for the combo we are going to run needs a 75mm maf not a 73(the top end of the engine is a trick flow track heat kit). Should i send the meter back or is it going to work. Building and tuning a fuelinjected motor is new to me so any info is greatly appreciated.

the c&l meter uses calibrated tubes inside the maf to determine the injector size. yes you still use the stock electronics

as far as it being too small, if your running a 70mm tb or smaller, the 73mm maf will be fine. the maf cant flow more air then the tb no matter how big it is

make wure when you change the "sample tube" you face it the right way.
the smaller opening faces the filter.

first they only make a 73mm or a 76mm one..and if you paid for a 76mm then that's what you should had gotten...
