New cam/intake power....any guesses?

I'm running pocket ported / gasket matched TFTW heads. The 625 Road Demon does have an electric choke that I need to keep as this is a street driver.

That cam and intake will get you some ponies for sure, especially with TF heads on it.

I'd be curious to see what a bit more carb would do for ya too. Anyone have a 650/700 you can throw on there to try?

I'm gonna go play with your combo on my desktop dyno, be back in a bit...................

OK, here's the skinny. With what your running now, I'm showing 361HP @ 6000. Cam is CLOSE to what you have, don't have the exact cam file for that one. With your new cam, I come up with 373HP @ 6000. Hang a 700 CFM carb on there, and we get you up to 378HP. This is of course flywheel HP we're talking, and on a computer to boot. I can't put in the exact intake either, so I used "dual plane 4bbl" for both scenarios. We all know that that differs greatly from "real world" horsepower.

You're probably gonna see your expected 20HP increase! Also, when you go to get rid of those 1.7 rockers, gimme a shout!
