For all you guys that voted 904 I would like to know how you are bolting them in to a V-8 car this is a Slant Six trans bell and all. If you were going to for for the baby unit your choice would be 998 or 999 but the internals are different between these two. I vote 727 for street performance. More durable for pulling hills and extra weight like the wife, cooler and chairs to the shows.
