I think that’s it I’m not hiding anything lol it’s nothing super special it just sounds it lol. I’ve never driven anything with this engine in it to know how it’s gonna act. The trans was in my 67 Chevelle super solid shifting chirped 2nd. The engine was too but the hydraulic flat tapper cam started to eat it’s self so I pulled the engine for a few upgrades and sold it as a roller.
