IMO this is the best you can get...

1. Make your own mounts
2. Yes a 700r4 is alot longer than your stock transmission. So that means a shorter rear and a longer front driveshaft.
3. To save some green, S-10's and Blazers had 231's mounted on 700r4's so you dont have to buy an adapter.

First: SBC + 700R4 is the SAME LENGHT than your 4.0 I6 + AX15 (or NV3550) which means you keep your actual drivelines.

Second: S-10's and Blazers never came with 231's. They came with NP233's which are different system. The inners are interchangeable but they are not 231's starting by the fact the 233 has a 5 bolt pattern and a 231 has a 6 bolt pattern.

those look insanely tough but they say that they are for a YJ. Will they work on a TJ?

These wont work on a TJ (maybe with a radius arm front suspension) but not a long arm 3/4 link or stock.

Those look like the ones that Advance Adapters sells as their "Offroad" mount for CJ/YJ

TJ to SBC mounts:
713090 SBC to TJ 4 cyl. https://eshop.advanceadapters.com/co...090-713090.htm
713091 SBC to TJ 6 cyl. https://eshop.advanceadapters.com/co...091-713091.htm

I'm running a RE Long Arm kit. o wonder if they would work?

[crusty1007]

You may be able to make them work. But I would be apprehensive. They may need to be modified. The TJ frame rails have a bit more of a roll to them to clear the front axle than a YJ or Cj.

[mongrel]

I wonder why the SBC to 6cyl needs a cradle?

[crusty1007]

They both have the cradle

[mongrel]

yeah but why?

[crusty1007]

The crossmember/cradle ties both frame rails togeather allowing the engine to use a stock style GM rubber mount to support it. I think the main reason is to be able to use the Stock GM replacement rubbers that way you are not searching for some random mount.

First....your right on the first part.

Second.....your wrong on the second. 89-91 s-10 blazers DID come with a 231tcase. In fact....it's a called a 231C case.....and in fact....they also came on certain models with a 231C HD model that had the beefier shaft, gears, chain and 6 planetaries. Oh....and yes....it's a 5 bolt pattern.

Third....the mounts you quoted from ebay...are MORE engine mounts. Give them a call, go to their website. I'm sure they can fix you up.

Linkage for shifter, yes.

Slip yoke....nope. Same as the 231J.

can you make the linkage work easily?

Best bet is to get the linkage from the s10. It works well and fits in the jeep easily. It would be cheap enough at a junk yard.

As for making the the linkage work.....you might be able to get the linkage to hook up to the mounting bracket....but the bracket on the 231C is totally different than the 231J in the jeep. Again...probably not worth the hassle if you can pull one from the junkyard for 10 bucks or so.
