255/290
Well after looking more into it was running way lean most of the time and switched to way rich under full throttle. Basically its been ran hard all its life and hasn't ran well so it's worn out. Last time it put down 300 was in 2004 so it's understandable. Going with a Teksid block, all forged internals, my Fox Lake PI heads, Trick Flow intake, and some custom grind blower bullet cams. Starting that this winter when I put her up for the season.
