[QUOTE="Modular Racing, post: 9992047, member: 18904"] Also, the guys here have given some good recomendations of things to look for and change, the 2 1/4 exhaust tubing is not good and a large restriction, there is a reason that 2005 + vehicles come std with 2.5 " tubing and they only make 260 to the rear wheels! The air fuel ratio is also not where we would run a HIGH HP n/a motor either, this engine should be in the 12 A/F range. And a question for you, was timing added until the engine pinged, if not, you will never know if this engine has/had enough timing (as a FYI this practice should NEVER be done with a forced induction application). Remember, you cant expect an engine to make more power if you cant get more air into it and out of it, everything else in between is just a waste of time if one end or both are a restriction- a great example of this is take a 1000HP n/a motor and add a 76mm Turbo that can support up to 1000HP- guess what- it wont make even 1 HP more peak HP with the turbo- FACT!
