DriveTrain / Aftermarket automatic transmission for my 77 Y82
« Last post by kra9484 on May 24, 2016, 12:39:12 PM »
Looking for some advice please. I have a 1977 Y82 Trans Am with the Pontiac 400 & automatic tranny (does NOT have the W72). I plan on doing a frame off restore once I get everything figured out what I want & who I want to send it to (RMC, Texas Trans Am, Florida Trans Am, etc. Any advice there also). I want to build up the engine to around 400 hp which I read is pretty easy to doÖ so my question is, what is a good replacement for the stock tranny? Should I rebuild it, is there a better aftermarket replacement? I called Tremec but they donít make any automatics. I thinking I want overdrive for long trips but definitely need it beefier for the higher hp. Thanks guys. Btw I did a search in the forums from years ago & found out about a 200R4 but looking for any more new info.

Possibly if beefed up in their mounting and foot area and possibly even extended back further to give an extra inch or so legroom. But then it couldn't be sold as a GM restoration part either.

If you can try to get originals, there are a couple of places that sell them (not sure if i am allowed to post them here). I have 2 aftermarket RQPs on my formula and another set on my 77 transam. There is a problem with the side marker light holes.. they are cut wrong and the marker assembly does not fit well. Basically you will have to do a bit of trim work on the edges. If you dont, they will 'almost' fit but will not seal correctly which in turn lets water in your trunk. If you grind off too much then of course you ruin the edge for the rubber gasket to seal out water properly. If you decide to go aftermarket and run into this my advice would be to test fit often and remove as little as possible to get those pesky marker assemblies to fit correctly! P.S....  the set i bought came from Ames, though I doubt it matters as I think they all get em from the same manufacturer.
DriveTrain / Timing

I'm sure this is a common question but I don't seem to be able to find the best answer yet. I'm wondering what a 1969 Pontiac 400 with a mild cam, bored .030, planed block and rebuilt 62 heads, Holley 770 carb, running 11 to 1 compression, what should my timing be set at.......
I've been playing with it at 10 degrees initial advance and now 25 with vacuum advance hooked up. I get spark knock if it's any further advanced with the vacuum hooked up. It seems to run really good at the moment but I still think it could be pulling more. I'm going to foot the bill and try and get it dyno tuned but it's expensive where I am and it's a 3 month wait at the place I want.
Anyone got any suggestions or should I just be playing with it till I'm happy.

Mines the 403 and just blasted it as well.  Soon I will send to Powder coat and asking the same question.

Thats a shame, there is certainly a market for them.
Restoration / 78 T/A fan color

I've just finished sand blasting my radiator fan. I'm prepping it for powder coating. I thought I would color it black. As I blasted it, I thought the blades looked gold. Anyone know for sure what the factory color is? My car has the 400.

Maybe I should be asking a different question. If you had this info in hand what would your follow up questions be? What should I make sure of before looking to go forward?
