    Th400 conversion e-prom changes?

    Thanks for the prompt response. I went and farted around with the car a bit and the gear change and timing change are very very close.

    Th400 conversion e-prom changes?

    Converted my car to a 400 over the winter. Everything is done and ready to drive. However... first and second gear are a slightly different ratio than the 200 that was in it. And I'm still using an eprom, one of Eric's chips. The pts extreme that was in it had no electronics and I relied solely...

    Drive line opinions and info welcome

    I appreciate the input fellas. It's a three and a half inch unit that I bought from kirban by a company in New Jersey. I think I'm going to contact " the driveshaft shop" and have a chromoly one built. Good thing I kept the tube this thing was shipped in LOL as I'm sure it will not sell locally.

    The converter will be a PTC and I already have the yoke. Waiting for the trans to show up from Rossler so I can install it and get a true measurement. Just going off of what I've read on the amount of material you may or may not need to take out of the Driveline. Never been overly happy with the...

    Drive line opinions and info welcome

    After spending quite a bit of money on as much lightweight rotating Parts I could buy, I have a dilemma. Towards the end of the summer I hurt my 200, and this next year the car will be seeing a lot more track time so..... I decided to go 400 over the winter. I have a really nice next to New...

    It changes full throttle shift points. Car drives the same under partial throttle. I left the large weight alone.

    I weighed it, after some testing with the scale I used at work, it had more accuracy at a higher weight range. So i weighed the entire governor assembly after i removed material. I have data on weight removed but not actual (small weight), weight. The final mod list was 8 .125 holes drilled...

    Where is the ideal area to remove material from the small weight on the governor? Have read people drilling holes, and grinding material away, haven't seen any pics, if anyone has some I'd love to see. Thanks in advance.

    Boost backfire rough idle

    Thought I'd get back to everybody with a good Buick life lesson. Always sucks when you read posts, and know the guy fixed his problem but never posted what it was. After replacing the ccci connection, the car still backfired. I found the problem.....my brand new ac delco coil was toast, also my...
