Default LT4 dyno results

Put her on the rollers this am and she put down 298.2 hp and 309.9 tq corrected to the wheels. I was hoping to see 300, but I guess more mods are in order... The hp and tq curves were nice and smooth, and a/f ratio hovered just around 12. Mods in sig

Not at the rear wheels -- the LT1's 300HP rating is at the crank. LT4's are rated at 330HP at the crank and typically dyno around 300rwhp.

A/F is a little rich. You could pick up around 10 to 15hp if you lean it up a bit. Dave 90zr1 #952 modified :reddevil

Mine put down 293 with less mods than yours so that seems about right.
