What type of dyno did you use? I would not be disappointed with nearly 600 rwhp. I am planning on swapping out my blower for the KB 2.6 and I am also going to put in either Crower or Comp Cams. I am hoping to see somewhere in the ballpark of 600 rwhp.
Thanks for response. The car has ben sitting for a few months I live in VT so when I run a tank of fresh gas threw it may help. I can't wait to try it. kenne bell said to run 23 degrees of timing we tried 21 and it only gave 19-20. I my try racing fuel to see what I can get.
My 04 Terminator put down 589hp & 547 torque on 17#. I have a 2.2 Kenne Bell with alot of other bolt ons. Check out my mods in the member gallery and you can compare to see if you think you should have better numbers. All my tuning was done by RWTD in Mobile, AL. They are one of the best tuners in the country, which might have something to do with the numbers. Hope this helps.
