Quote: I had my stock 67 HP440 rebuilt using basic stuff, stock valve job, eddy 750, comp cams 275. 2800 stall and 3.23, which is an issue. It is a dog. Have to turn the wheels to break traction. Trans has shift kit and it will occasionally chirp, but I was hoping for more. Stock intake and hp ex. Manifolds. I am pretty sure my 2007 Avalanche would blow its doors.
Then something is wrong, my R/T has a smogger with it's 727 and the original 3.23 sure grip and it will light L60s at will on take off with just tomping it, much worse if I flex it up against the convertor and literally destroy them if I do a brake stand.
