Building reliable Street horsepower that was able to drive on pump gas and idle in traffic was a goal for this project. With that in mind we started designing compression and cam profile to meet these goals. dyno test will run on 93 octane and progressive linkage corporation just like he's going to run on the car. One thing nice about the design of modern combustion chambers and aluminum heads is it allows you to pull back some timing and add more compression to more effectively use the air fuel mixture that you have. Where as an iron headed engine at 10.5 to 11-1 is not going to be conducive to running 93 octane pump gas, modern combustion chamber design aluminum head allows that no problem. Cam profile and design also help with how the engine's going to behave on the street with pump gas. This is where we called Dan Rawls at Cleveland performance in Cleveland Tennessee. Dan designs most all of our cams using car weight, gear ratio, desired intent, and many other factors that will come into play. We very seldom ever use off the shelf cams because we design our engines to fit the customers project. Final result on this engine what's 606 horsepower and 665lb of torque. customer was open for high 580s on horsepower one thing to note are long tube headers did not fit on this project when we put it on the dyno. because of this we had to run shorty headers which probably cost us 10 to 15 horsepower and the equivalent on torque. So look at the pictures below and enjoy them and we hope our customer enjoys this project as much as we enjoyed building it.
