[Cuda340]

So call me crazy but I?ve sold my Stock eliminator 1970 340 Cuda and going on an adventure that I?m kinda excited about,have purchased Danny Wilson?s 1974 Buick Apollo J K L/SA stock eliminator car out of Illinois from another individual that bought it out of his estate,past owner has gone 3/10 under,looking for recommendations on the go to guys for these Cyl. Heads and how good are these cranks, blocks,can you take them .070 over safely or as I suspect a sonic checker needed? Thank you in advance?Chad
