LOL! My 2.5 isn't that quiet either when revving, even with a BFN exhaust.Lol for sure it is nice to have progress. Surely hope it’s not fake progress and that I find the leak again after running it more we’ll see. I’m just glad it starts up after all this time, good oil pressure with the new pump, and it sounds just like it always did. Revved it up and it sounded exactly as I remember from all the years of driving it.
Crazy how loud that 4.0 can be when reviving it in the garage.
But I can tell you It's a hell of a lot quieter than a 2.0 Ford @ 11:1 compression with a Cherry Bomb!
That motor absolutely Barked!
