I had a 305 cam added to my engine rebuild a year ago. Builder said its a 355 now and engine was blue printed and balanced. Had it dynoed and it was weaker than a stock engine.(Less Horsepower).Computer was sent to pcmforless after dyno and same results. Can anyone tell me what i need or what i need to check out.I pissed because i could have brought a crate engine. :mad::(:confused:
