but u can drill a 3 inch hole in the box and use a piece of 3 inch ex tubing as well and just glue/seal it to the box .
from there u clamp ur maf sensor onto that then u clamp the vac hose onto the other end of the maf .
be sure the maf sensor is oriented so that it reads flow from the box to the shop vac
i forget exactly which maf sensor to use but u have to supply 12 volts on one pin and 5 volts on another , one pin is ground and then u take ur reading with the dvom on the reminaing pin witht he dvom's positive lead, the dvoms ground lead just goes to were ever u have the maf grounded to more then likley ur 12 volt power supply
if this is something u will use a lot build the box out of steel instead as it will last alot longer from the continuous bolting down and unbolting of the cyl heads
Wow, thanks for the step by step. I really appreciate it and if it looks like I'm going to be doing more heads in the future I will actually give this a shot in the spring.
