What is your static CR? Trying to compare it to mine as I have a VERY similar camshaft along with ported and milled heads.

515/466 on pump 93. 560/520 on E. I've heard that E stuff is magic. Ain't it????

Get the dyno dude to start the pull at idle. Makes for an interesting dyno graph! Before my current dyno, I've never seen one started that low.

I have a nice clean Dyno Jet chart that starts at 800 rpm. What did Holdener say was the problem with starting that low?

The pull started at 800 rpm in 4th gear?

Aren't DynoJets chassis dynos? I stated ENGINE dyno. Like on a stand dyno.
Holdener did say chassis dynos can go low due to the different way they load

Yep. It pulls good on the highway from idle in 4th. I've never seen a dyno graph like that either. Every other one I've had on a dyno starts higher.

Well I was a few ponies short but still nailed the goal. Darth_V8r is the man. Keep in mind I have 281cc stock ported heads so this is not optimal by no means but still produced a very meaty average power band for a 226/236 cam.
