LOL you're all fast learning after many years of me trying to educate you all, why I recommend the 1600 bottom end when using a cvh head.

They don't pull peak power until 7000rpm and then still hold at least 95% peak power at 7500rpm. Total power band is 3500 to 7500, and combined with a relatively flat torque line, allows you to use the power without excessive wheelspin!!

I do build big capacity engines as they drive well at lower rpm's, but I personally dont think you can beat the all round characteristic of the 1600 when keeping with the cvh!
