I run an A9L from an 89 in my 1986 GT. It's a stock longblock with boltons. Works perfectly with the Typhoon intake and 65MM TB and 70MM Cobra MAF and headers, etc. Only problem is by a little past 6000 my car went way lean at stock fuel pressure with 19lb injectors. I remedied this with an adjustable regulator and more fuel pressure and a little less timing advance.
