We'll see how mine does at altitude now that I have a wideband. Last year I guess i was running SUPER lean, even though plugs looked decent. (By decent I mean they didn't completely melt).
408, 11.75:1
Trickflow heads
Super Vic
Howard's solid roller 257/267 .640/.645
4.30, 4800 stall converter (not built for this combo).
It didn't run that great last year. With all the tuning issues I had, but not bad for the elevation.
