Was it just a dyno run or a dyno tune? Try to see what the A/F ratio is and where you need to add/subtract fuel. Makes all the difference.

damn that is really low. id expect to see 320+ at the wheels. What is the grind on the cam? Also those AFR's might be holding you back. Most AFR heads i have seen have really crappy intake to exhaust ratios. You might want to consider some better heads, maybe some Brodix or Darts. Even GMPP aluminum L98 heads have better ratios.

 

I've heard that Crane makes some crappy cams for our cars. I've seen the specs on the catalogs and they don't seem very big.

theformula is right. I went to a dyno tune and did my pulls with a wide band O2 sensor. I was running real rich. I pulled out my Ed Wright chip and installed a new chip that a local guy just burned based off the readings. After 3 pulls, with some adjustments in between, I picked up 15 more HP.
