I'm with ya on that guess. I don't think its got enough camshaft to go 7000+ in it.
Im thinking somewhere in the 900-950HP range, peaking in the mid 6000's.
Single cat, if I recall, this was gonna be around 11.7:1 to 1 compression, and were you going to be running race gas?

Last pull for the day. Got to put a little fuel in it. Thanks David Nickens for the killer engines and Jeff Harris for talking boat engine stuff throughout the builds. Just a 1000 hp on pump gas strait motor

Making some steam for sure! Looks like its not lacking torque with the big heads either. Did you guys do any pulls below 5k rpm?
I didnt think it would have made much power past 6500. Did you guys leave the lash to .022?
Great build, looks like your builder hit your goal

To me the most impressive part of the hole build is that that the cylinder heads are out of the box with cnc chambers and a vavle job. Only thing David did was going in there and tootsie roll it up and clean up the casting marks. Same thing for the manifold it's literally out of the box with absolutely no Port work just clean up work for the casting marks.

id love to see the numbers from 3500-5000. My guess is its making more than enough torque to get a 32 skater up and flying

We made one pull down at 4500 but i cant remember the numbers off the top of my head but it was mean. David add more water to the pump. He said he dont like pulling motors like that down low because its rough on his pump.
