      LS dyno

      Had the engine dyno'd Thursday night....she hit 421 to the tires!! A/F ratio dead on!! It is a 5.3 punched to 5.7 forged bottome end, PRC heads, torquer V2, Holley 750 ultra DP with an Edelbrock performer intake through a 5 speed abd 12 bolt. I am pretty impressed. It made 80 more horse then the old school 383. My 421 was at 6700 and still climbing! Best part...this thing is drivable. I have had this 69 camaro since 92 and it has never been this enjoyable!

      Nice numbers!!!! I have been contemplating installing a torquer v2 cam. How are its street manners?

      ^...In addition to the questions above, what LSA is your cam and your static compression ratio?

      Thanks,

      Street manners are extremly good. The car fires on first try and I never have any trouble. my compression is 10.8:1. lobe seperation is 112. I had the motor built to handle forced induction. I was planning on a magnacharger next year, but this motor looks so cool and has very good power, so who knows. The motor is built to handle what I throw at it...i wil get a video of the dyno posted when I get some free time.

      Nice numbers! Which PRC heads are on the motor? We have always had good luck with the torquer v2 for a driver.
