Ok here is an old one Landy gave me on the phone, 360 .030 over,13.6 -1 KB's, 580-600 crane solid, ported 308 heads , M1 Intake 830 Holley 2 in open spacer, ran 10.80's good air @ 3600lbs. You tell me how much HP it was. Same combo with Ross 10.5-1 and Crane 540 -560 cam ran 11.30's. Back then I couldn't keep head gaskets on it with high compression so went down to 10.5-1
