RevLine89 thank you! Yes it was but it didn’t work well though so I had to replace it. It’s a ”daily driver” and I didn’t get any vacum for the brake booster.

@@ifixmycarmyself2502 :/ oh that stinks! i have a set of these for a 4.6 mustang someday i want to build hopfully they work

The car is a genuine T/A but original engine is gone long time ago. It has a 340 with 6-pak and a Comp Cam "big mother thumper" in the clip. The following year i replaced the cam with a calmer due to idling problem and so on.

@@ifixmycarmyself2502 that’s cool. Yeah some cams don’t generate sufficient vacuum…especially for things like power brakes.
