Holley has the new 900 cfm Xflow out so we got one to test. Ran it on a 505 inch big block and made right at 700 hp. This is a pump gas engine with Trick Flow 270 heads, a Comp street roller cam and a ported Indy intake.

I think the cam is 260/266. It isn't really big and it is a street roller not a race lobe. Heads are out of the box Trick Flow 270. I think the CR is 10:1 or close to that.
