Good to hear Doug!
You know - because you been doing this stuff long enough - but I'll say it anyway because lots of folks read this threads - and some don't know - the effect those 28" tall tires have on the final gearing. The 3:08 is probably more like a 2:97 or so with that tall of a tire.
I was really laughing about the "pig motor" comment.... and then you do the combo - higher stall converter - tall tires - 3:08 gear.... yeah -- it'd be a pig. But that 120 on the freeway at 3000 rpms says it all.
I had a brand new set of headers leak once - locally built here by a super good header shop - had 'em ceramic coated - installed - and the dreaded tick tick tick... took me about a week to find it -- the "star" where the four tubes come together at the collector was leaking! You can't get in there to fix that without whacking the collector off. Lucky - the shop took it back and gave me a new one and even stood up for the coating. I buy all my headers from them! That's just good business!
