Ok, so aside from the basic tune up I see that it is written you don not need a heads and cam and or 383 to have a fast and fun bbody. If I read correct its written that with a cold air intake system, valve springs, 1.6 roller rockers, tconverter, headers, cat back exhaust, gears and tune a fast and fun bbody is attainable. Well I seen a good deal on an auburn posi carrier with 3.73 gears so I picked it up for $300 dollars awhile back but have yet to install. I would like two different opinions here I would like to know in what order should the remaining options be purchased with cost not being an issue.second, for someone one a budget trying to buy these items by cost first wich route would u do this? Thanks for all who comment.
