Stock Stroke 340 Build with NC Engine Builder
I would have loved to have been there for the pulls but not to be. I guess the session had several challenges with the equipment but the engines ran well. We didn’t get all the data we had hoped for but I’m solidly happy with the results. The 750 dyno carb was leaking and had to be changed for Shawn’s shop 950 Holley, out of the box with no tuning. Even with all that, the motor made 439.4 ft-lbs @ 4300rpm and 457.8 hp @ 6300rpm. The oil pressure is superb, as it should be with good bearing tolerances and the bushed lifters. The HP hadn’t peaked quite yet and may have had a couple more with a couple hundred more rpm but he didn’t see a need to push it. I have not idea what the timing was or if it was played with and maybe he can comment on the runs.
Edit to add chart for better visuallization.
