Combo's that work 454, Solid Roller Cam
I am searching for hydraulic roller cam for my 454 (.060, 468CID). I have a solid roller cam now. I have a combo that works rather well, I just don't want to pull the valve cover to check valve lash several times a summer. The idle is fairly smooth for a solid roller cam.
The issue is that I don't see a lot of these with actual dyno results. So here are mine. I only have Rear Wheel HP and TQ numbers.

I did about 15 pulls total to get the correct jetting and 4 more pulls after we got it tuned in. I kept two of the dyno sheets. We tuned it with a wide band 02 sensor and kept constant fuel pressure (7.9 PSI Average) and Air/Fuel Ratio (12.6 Average) throughout the RPMs

This was on a Mustang (Branded) Dyno in Omaha Nebraska. Keep in mind that these are Rear Wheel Ratings not at the engine. Rear Wheel HP is approximately 18%-25% less than crank HP.
