the 77's upgrades

[chuzie]

The 302 has a max long term sustained RPM of 3200 and max intermittent RPM of 4400 which is where the 210 HP is produced. He will likely cruise around 2500 rpm which is pretty good.

I've been reading a lot about his on Classic in the last couple of weeks. There are several guys who are in the same boat as you w/ their NV3550s. They are rolling 302s, like your 77 correct? I think it really depends on what your RPM is in that 5th gear. Once you find that out you have to know if the horsepower in ur engine can perform in that band. I've waiting to find a thread using a mild 351W using that same tranny. Don't want this tranny if my 351W eats it up from pulling someone from a mudhole. My opinion if you are wanting a DD, go with 4.56s. Go 4.88s or 5.13s if you wanna have trail fun OR wanna go bigger tires down the road. I'm glad you got this tranny first so I can learn from ur mistakes!!!mokin: Either way this is going to be interesting and I wish you the best of luck. Hope it goes in easy for ya!
