Without reading the entire thread, what was the horsepower target on this motor?

I know you are probably busy talking people back from the ledge as the markets take us back to the stone age, but you don't need to read the whole thread to get the details, just the first page.

150-170 is the target. I'm hoping for the high end of that figure.

There's a cool calculator on Wallace Racing's website that allows you to plug in the CFM of your heads, pick a general class of cam, plug in a displacement (in cubic inches, you'd need to convert), and number of cylinders-- then it spits out a HP number.

It's not perfect, but gets you close. My numbers come up in the 168 hp range (@6400 RPM) using the "street/strip" choice, and 182 hp using the "typical race engine" choice. With the cam I've got, I don't think 170 hp is unreasonable at all.

The heads will limit anything more-- it'd take 180 cfm to get to 200 hp at this displacement.
