I would like to replace the stock 2bbl on my 87 Ramcharger with a 4bbl. What do I have to consider? I'm wondering about head compatability, and other related issues. I think I would like to use a stock intake/carb if they are available, please advise if you know which years to look for. or an aftermarket intake would be ok if were ok for basic street use. Any info is appreciated. Thanks, rogerramcharger
