Had a 283 in my 56 coupe during high school and ran exactly what Czechman said. I ran a Duntov cam(correct about Arkus) with a nice Rochester and if I remember correctly we bored it to .120 to get the 301. Back then most folks said it couldn't be done but let me tell you......it was a "haint" back then. I didn't sweat anybody in my class and most of the time had to run "over my head" to get someone to race or at least spot them a car lengh or two.....of coarse I didn't run around town tellng everyone what it was bored to ect....OOOh, the good old days!
