Currently 3.23’s factory weight(around 3400 I think), current tire is a 225 but going to a 12.50 soon, stock converter I think, 360 bored .060 over with roller lifters and rpm air gap manifold and headers. I know the gear is a bit tall, but I also need to have decent rpm’s on the highway. May go to 3.55 or 3.73 when I put the bigger tires on.
