to build or to let be

ok. im putting back together the /6 in my 68 that my brother took down to a long block and just kinda gave up. my real intentions are to drive this car for a year or so and im going to build up a big block for it..... ( i know i know....) so anyways before the tear down i had a offy 4 barrel intake and clifford split six headers and the carb was a holley 390 dual feed double pumper (i just thought cool!). so i want a little pep to the motor but i dont need anything impressive. the head has stainless valves stock size and a gasket match port job. maybe a small cam? i want to be able to drive the car alot and do some highway driving. so losing driveability is a no no. any suggestions guys? :thumblef:
