Dear J/K;
'Gramps' is right, it can be done. Back then gas was a quarter though.
Look for a 261" bore to 278 CID + a 4bbl & headers will work in a 56 just fine.
Your $ cost will be $3,000 +/-. In the 2 yr it will take, you'll learn more than any 'Auto Shop' could teach.
"Happy Trails", John M.......
