LOL YUP. actually it has 15k on it and one one edge of the metal there is a hint of rust. have to take it off and fix before it creeps around the edge and you can see it
I swapped a 4.8 ls with a mild cam and 4l60e into my 86 442. It dynoed at 300 whp (double what the 307 would have put down at the tires). I get 20-22 mpg on my daily commute (307 was in the high teens) and the cam gives it a nice aggressive exhaust note without being too obnoxious.
IMHO.......it is better now in every way compared to stock.
