Set up a dyno day to test some new ideas with the N/A stock 302 short block, H/C/I. Testing was performed on a Dynojet. The premise of this particular test was to expose if an increase in flow i.e., intake porting, in the intake tract would create a gain in power. The test was skewed because of a few factors that arose during the testing. I believe the fuel utilized was somewhat dated. (lack of preparation on my part). And a malfunctioning fuel regulator that would not allow an increase in fuel pressure. The facts that were drawn were concise. Without being able to compensate with the fuel a severe lean condition occured. A tune is in order so the A/F ratio can be dialed in for maximum power, along with other variables. The A/F would plummet around 4,800 rpm. The test was conducted in an rpm range between 3,000 rpm to around 6,600 rpm. At the shut-off point the a/f was near 13.7-8 The differences between the 2 Holley SM II's will not be divulged because of the skewed variables. Looking forward to the tune and freeing up more power with driveline modifications.

Best numbers for the day were 385/365 The goal is to try to hit the 400 rwhp mark keeping the circa 1993 short block in naturally aspirated form and not modifying in any way or shape.

In conclusion, using same day dyno testing revealed the weak points when the combo was altered somewhat.
