Haven't been on the site for quite some time? Have a question about building my 6" cowl hood with a pro stock scoop grafted on top? If I put the PS scoop on the cowl do I need to close in the back of the cowl? Curious about under hood pressure if I'm ramming air through the scoop? Car has been completely rebuilt with a full tube chassis, a 406 sbc running 10.20's at 129. Any help or info would be much appreciated!
