[Mr 5 0]

FWIW: I owned a 1990 Mustang 5.0 which saw many street races under my 15-year ownership. The 302 (C.I.) engine never gave me a moments trouble in the 125,000 miles I put on it. To be honest, I changed the oil and filter every 2,000 miles and never went into the redline, all of which help an engine's longevity, I'm sure. The Mustang 'modular' 281 (4.6L) V-8 may be a tad less reliable than the (earlier) 5.0 V-8 but is certainly more reliable (and fun to drive) than the V-6, which is rather 'primitive' in some ways - and has to 'work' harder, too, just to deliver less performance.
