Need bell housing adapter for ls swap..1970 olds 442
Well my shop is ready to install my BRAND NEW LS engine. However, the bolt pattern on my turbo-400 transmission does not match the engine. The LS engine bolt pattern is designed for a chevy turbo-400 transmission..ugh!!! 
Come to find out olds,pontiac and buick have a different bolt pattern compared to the chevy turbo-400..So they are saying i need a BELL HOUSING ADAPTER for my transmission to make this work.They are having a hard time finding an adapter...So does anyone here know where i can find this adapter???

I can't believe I am helping this swap but get something stronger like the Transdapt adapter. I had that flimsy one on my 8.5 to 1 307 headed Olds 350 connected to a 4L60E. I could only fit 4 of the 6 bolts on the cheap one like that. This one is notched and has the reduced head bolts.

If you are going through all of that why not put in the matching 4L80E trans. See how easy I spend your money. Truthfully if the BOP 400 isnt fresh you will likely be replacing it shortly. Why not do it now. Plus you get overdrive.

Hell yes. Do it now. You have committed this far. Do it right. You are shooting for a modern drivetrain car. Do it. Bank is obviously no issue. I would step up while you are there anyway. You will love it that much more.
