Ok, I'm wrong. I was thinking 1986 was 200 and 87 up were 195. Oh well. When I was done with my own it was a bit better than that but I never had it dyno'd so don't know exact numbers. Assembly was balanced, ported heads, Crane CompuCam, 1:7 roller tips. Got rid of the push rod guides and went with screw in studs and tip guided rockers. Exhaust was new H pipe, headers (FMS), and a Flow Master cat back system with brushed stainless tips because the early GT didn't have the skirt and those beautiful pipes could be seen. I always thought the 86 GT and later LX cars looked better than the later GT's and they didn't have all the weight of the extra GT trim.HK, factory HP on a 86 was 200. Most 87 up's were 225.
