mornin everyone. i have a 1951 chevy 3100 deluxe pickup im resto-modding. (Henry Panza S10 frame swap kit) . i picked up a (unsure of year)283 with "520" power pack heads (came with 2 bbl intake but i have a 4bbl intake to go on it .) to put in it ,looking for advice on its near future machining since #8 cyl needs some clean up cutting (hoping for no more than 0.030 over). No intention of racing , just a nice driver.
