Here's an intercooled roots 8-71 547ci at 8.1 comp, running 10 pounds of boost on pump gas w/ Brodix 345cc intake runners setup this Winter by YPM. Dyno was performed w/ accessories and wet CMI E-Tops.[/QUOTE

What cam is in this? Off the shelf or a custom grind, solid or hydraulic?
The cam is hydraulic, that's about as descriptive as the builder would get. I guess cam dimensions are fairly important.

john,what cam did you decide on for these engines and what carbs?also will they be innercooled.
I have 1075 sci cams however Jim V wants me to use the grind he put in the 540 sc builds that made really good power. I'm starting out with just 850's but will more than likely end up with some QF 1050's.

I'm holding off on intercoolers to start with but plan to add later. My original builds were going to be NA but I changed my mind last minute so got caught off guard with additional expense that I hadn't planned.

Sometimes cam grinds can be like giving away your favorite mushroom spot. Lol. That build is very similar other than Jim v raising my floors. I didn't think in a blown application it would make much difference but evidently it does. How much who's to say but....
