Not practical and a lot of work to put a race engine on the street,you might find someone wanting a race engine and find a stock 250 to build for the street.that much compression with a big cam will load up on the street,and race gas is a must,trying to tune a race engine for the street isnt worth the drivability problems.If that engine has good parts you could trade or sell it for enough to build a nice streetable one.just my opinion.
