Chevy 283 bored .125. What a sweet sounding engine. Man those engines can get the r's up. I also like the early corvette 327's, 340 365 & 375 HP engines that's what a engine should sound like. And of course the 426 hemi there is no equal. Unless you consider the 500 inch funny car motor (John the main man Force) When those cars go by you can feel the power go right threw your body. Rich
