My LQ9 408, built 4l65E, 3600 Yank, 12-Bolt 3.73
Cam Specs: Comp 243/251, .624/.624, 111+1 LSA AFR Mongoose 230cc / 62cc ; 11:1 Compression
This was through a Borla ProXS muffler
I know doesn't look impressive but runs harder than this Dyno Sheet shows, pulls hard 3500 - 6500.
Like Chad the owner of The Shop Inc told me when people clown on my dyno numbers, "just tell them lets line them up" lol
If it means anything he's had some LS7s dyno higher than mine and some that dyno around the same or lower.
But if your 408 broke 600 rwhp then damn The Force is strong on that bitch!!
