I'm going to be converting my 4-spd. car to a 727 automatic and have a question about trans. pans. What I would like to know is whether or not it is a good investment to purchase an extra capacity deep pan for a street driven only car or is a standard factory pan sufficient? I won't be doing any racing so that is not a factor. Engine is a stock stroke 340 and the rear has 3:55 gears.
