And they were stupid quick, stupid expensive to fix. 90-93ish IIRC. 3" exhaust, MBC, AFPR=low 13's. Alas when you loose the oil pump, it eats the cams and rockers. 1300 for the set. The Rad was specific to the car so it could clear the FMIC, 800 bucks. It's a love hate sorta thing. Love to beat it, hate to fix it. Given the opportunity, I'd buy another. Ultimate sleeper.
