Id take a close look over the igntiion system, plugs, etc. I had a bad plug on the dyno. Still made 760 on 7 cylinders. Replaced plug, 818hp. Had the marine exhaust on so no egts to tell me

Final pull. Spark arrestor on, full marine trim, lightning headers. I will tweek the AFR's if necessary once I get it in the boat.[ATTACH=CONFIG]566370[/ATTACH]

As a side note. Made back to back pulls with and without water running through the chiller. I forgot to turn it on actually. Made over 30HP difference.
I have a Baker Engineering 7.5# mechanical pump on this engine. It is supposed to support 1200HP, but it won't keep up. 3 pounds of fuel pressure at 6000rpm with a -8 line in and out. Might have to ditch it for something else. I love the simplicity of it but ? Ideas?

Thanks, timing, jetting and valve lash. Found 70HP today It actually made a little better pull today with 35 deg timing and spark arrestor off, but not really real world.
