Inliners International Forums General Discussion Hi Performance New Guy Here. 68 Camaro with an L6 250.

Finally found out why I could never get the tune right!

My powerglide always shifted a bit rough but I was told "they all do that" and just assumed they all did that. Turns out the hose between the hard line and trans was, well, missing.

Replaced the hose, reset timing, reset idle air, changed to a #28 squirter and off I went! Problem solved!
