At least that crate has a cam that's matched closer to it's compression ratio.
The 290 hp engine has a mismatched cam with it's low compression. Look at this chart to see a relationship between cams and compression ratios.

I've read a lot of these threads before and a lot of people have been happier with the lower HP version because it appears the "performance version" wasn't optimized for performance at all and has most of it's usable HP in high rpm range. I want my power down low. It's a 4K lb brick.
