HI im thinking of buiding a 383 for my nova and was wondering if there was any better than others in years of the 350 4 bolt blocks or is a good 2 bolt enough thanks

20 yrs of drag racing brings about the following answer.The stock four bolt mains have a habit of cracking the out-board bolt holes.Unless you are going to convert a two bolt to a four bolt main with aftermarket caps,I don''t think it is worth the effort for a street application.
