BOP Th350 where to start.

[MrSony]

Hey all. Today well, technically yesterday at the time of writing this, I got my new Q-Jet from everyday performance (excited) and I scored a "shifted fine when last used" BOP TH350 non lockup out of a '79 T/A with a 403. Now, I plan on doing a filter, pan gasket, fluid and good 'ol degreasing to this trans, but what are your guy's opinions? Any tips or tricks I should/need to know about putting one in a G body with a poopy 200 metric? Never really messed with a transmission before other than installing. Fluid doesn't smell or look funny. Didn't see any chunks. The bracket thing on the side went through all the gears fine. Also toying with getting a higher stall converter. I imagine the stock one wasn't anything over 1500. It's going behind a Buick 350 with unknown power as of now, but I hope to get 'er up over 250hp (smog motor) when I get around to finishing it. Also keeping the column shift from my 200m.

It'll drop right in if you have the short tail th350 which you most likely have.

If the fluid looks good and the pan doesn't look like the clutches are in it go for it.

As for a higher stall I would call a trans place or someone like hughes transmission to see what their recommendations are. They'll all for gearing and cam specs midday likely but a at least you'll get done options.

Anyone know where to get torque converter to flexplate bolts? Don't really trust the ones that came off my SBB.

You can get them from auto zone or advance. They usually have them where their performance section is.

Pretty sure those will be metric bolts and you probably need 3/8" bolts anyways. I would go 2200-2500 for stall and add a Transgo shift kit.
