not a chevelle but its a v8 :)
 

well today a local group had a dyno day and some of the money was going to feed the less fortunate for thanksgiving. so i said i would go i always wanted to know what my Rx7 would do so being that my car has never been tuned before i said let me get on the dyno. man was that fun seeing people with the OOOO'ss and AHHH's when they popped my hood and saw my LS6 motor sitting in there. so long story short my baby put down 308hp with an impressive 317 tq :) attached is the dyno sheet

308? Thats it? What size is the ls6 in liters? ... that seems alittle weak.

The base unit LS6 put out 385 BHP and up from there .... you couldnt be losing 75 HP to your rearwheels could you?

Sounds like fun day. 308 at the rear wheels doesn't sound to bad in an RX7. I imagine it scoots along pretty good.

the ls6 is a 5.7 again my motor needs to be tuned and it was shown on the dyno sheet it was running super rich on the lower end and lean on the upper end. so yes i am going to get it tuned but in the spring. right now i am going to focus on repairs needed on the rx7 nothing major but i am going to do that first. then in the spring drop a good 300-400 on a good dyno tune and i am sure i will get back all of my power.
yes that is pretty good being that my stock power before was 157hp with 138tq :)
