I bought a Blueprint Engine through Summit Racing. The engine came complete and tuned on a Dyno by Blueprints assembly plant. They stayed at five hundred and eighteen horsepower and five hundred mainteen foot pounds of torque. I took it into r p m for the final tune and to fix some problems the installer caused. RPM tuned it perfectly. they got the timing just right and they changed out the main jets in the Holley 850CFM 4 barrel quadra jet carburetor. They're just at the linkage so that the throttle would complete WOT. They adjusted my kick down linkage on my transmission as well. These are all problems that the other shop could have corrected but they really weren't concerned about doing a fine-tuning. They just wanted to get the project out the door. My truck purs like a kitten, starts on the first crank, and produces maximum horse power. All this for just under one thousand dollars. This is well worth the cost.
