The timing is very conservative its primarily a streetcar and middle of summer not to mention the motor has some blowby under pressure so I was extra cautious with plenty of room for growth on track. The 7.5pressure with filter on would probably be around 10 or more on a stock motor but the holley intake and trickflow heads are great flowing combo for stock shortblocks. Also must be noted I have a eddy brake dyno so numbers tend to be lower than dynojets.... Jeff check the balancer and mounts to make sure none if the vibrations are coming from a loose bolt etc..
