Just when you think it's safe to peer into the HiPo forum I hit you with an update, and here I thought I was done with it LOL...

I've been wanting to hear what the Jimmy sounded like since the engine swap. In the cab it has a nice low rumble up to around 35 then the wind noise takes over. That is unless I goose it then the sweet sound of 600cfm of air being gobbled up by those 4bbls takes precedence. Sounds great but alas, no exhaust sound to be heard over the carb and wind noise.... 

So after putting it up for the day the daughter and SIL came by later that evening to drop the grandsons off so they can go to an after Halloween party as a couple of Grease characters. They floated an off the cuff request to drive the Jimmy to the party and I tossed them the keys. I thought they were gonna pass out LOL..... After some instructions and a fare-thee-well I finally got to hear those MagnaFlows proper. I likee.....
My daughter wouldn't let him open it up when they pulled out but I got him to when they came back.
