Anyone running a 700r4 trans in a 72 cutlass?

Installing a 700r4 in a 72 Cutlass 350 engine and wanted to know if you could still use the original crossmember? I know it would have to be adjusted but that's all I know.

Dunno if this is any use to you. http://www.transmissioncenter.net/Tr...asurements.htm

It's a hair over 2" longer to the crossmember mount.

The crossmember needs to be moved back, shorten your driveshaft and you're in business. Oh, make sure your trans tail shaft will accept the speedo cable.

Wondering why you chose the 700 when a 2004R is a drop in and has better gearing? In stock form they're really tit for tat.

The 2004R is a direct bolt in for a 72? Does that go for the '71 as well?

I never found anyone that wanted to build one. Everyone I went to always trying to sell a 700r4

A 200 will bolt right up to the Olds block whereas the 700 requires an adapter plate.
Overall size of a 200 is very close to a Turbo 350.

Gear spacing is MUCH better on a 200. A 700 reminds me of a Slim Jim in the 1-2 shift.

A 700 might take a tad more power than the 200, but as said, in stock form they're both junky transmissions- owing more to GM bean counters than really bad design flaws. Both were upgraded during production runs and aftermarket parts and ingenuity made both very tough and reliable units.

If airboddy wants to sell you a 700 and they'll stand behind it, go for it. But a properly built 200 is really better suited to a B-O-P application. Just my opinion.

Yes.


You are aware that the 1971 & 1972 are the identical car with minor cosmetic changes are you not?

I suppose you could call the B-O-P musclecars "birds of prey".

The 200-4R is the same overall length as a Jetaway, short-tail TH350, or manual trans. Even the driveshaft yoke is the same (except for the M22 with the large output shaft). The crossmember location is in the TH400 location, so even that bolts in for 1967-up cars (earlier cars didn't offer the TH400, so the frame must be drilled for that crossmember location).

The 700R4 is a unique length and uses a unique crossmember location.

Would you have any pictures on the crossmember bar. Having a little trouble finding a place for it.

With the 700-4R/4L60 you will need to drill new holes. Bolt the trans to the engine, bolt the crossmember to the trans, and mark where the holes need to be.

Drill holes through frame rail directly through the brake line hidden inside. Drop a razor sharp shard of rusty steel directly into your eyeball. Shriek in pain as you lurch forward and slam your head into something solid. Then go to the ER and have nurse Rached drill it out as you stare frozenly at the gap between her teeth.

Is that from the manual?

You may also need a shorter parking brake cable.

The trans rubs on the floor pans when I try to mount the crossmember. I'm trying to post pics.
