Here goes; 87 buick regal lq9, l92 heads milled .015, .040 head gasket. comp is 11.2.1, btr duals,l92 truck intake,ported throttle body,pat g cam at .050 224/232.629/.604 115+3,1 7/8 headers 3.5 to 3" exhaust with x pipe 3 "to the tip.2800 stall with a 4l60 and a 3.23 rear gear. 4"intakewith only 2 bends. Car dynoed at 400rwhp and 392 rwt. Seems a bit low. Bavent been to the trac yet cuz on the last dyno pull the drive shaft left the building. I know trak # will tell the whole story but just lookin for input. Will post a dyno graph what i get car back. Found out drive shaft broke at 12 and had new one at 5.
