[455Grandville]

My '75 ; great uncle and aunt bought it new. I got it in the late 90s with 20 something thousand original miles. It's been garaged it's whole life and I think it now shows about 35,000 miles. Wasn't happy with the 200 horse 455, so I replaced it with a 030 over 1970 455 I machines with 6X-8 heads (9.3 comp) with some pocket porting, 3 angle valvejob, Comp Cams 255 DEH, roller rockers, RARE exhaust headers, 1971 intake, few other things. The difference was night and day after the swap; I even beat a co workers 350 IROC in the late 90s after I installed the engine -
