1987 Dodge Dakota 5.9 swap with a NV3500

Thanks for the info AJ! It’s just a bone stock 5.9 I’m just gonna run a carb on it. Motor only had 50,000 miles on it. And is real clean. I’m thinking of running a 625 Street Demon. As far as the rear goes it has a 7.25 rear and I’m gonna swap in a 8.25 rear with either 3.55 gears or 3.90 gears. Gonna get one out of another Dakota. Some of these trannys came behind a 5.9 in a Ram from the factory I don’t know yet what this tranny came out of from the factory. I think the Ram has like a 4.01 first gear??? They were rated for the 5.9
