I tried using the 76mm MAF with the V8 sensor, but did not have good results. I ended up using the 68 mm MAF sensor in the 76mm MAF body, runs great. I plan on going back later and retrying the bigger sensor. I have since thought I may have had a leak on the rubber gasket. will post when I get around to it. I have been working on getting the 2.75" intake tubes installed correctly. I also made some home made devil horns, not quite the same as the ones you buy, but seem to work good. Have get some more clamps. Thinking about some way to insulate the tubes to keep temp down.
