[Hey Brian, leaning more towards the r150 as they seem to be fairly easy to locate, may even run the chain tcase at first and then get the v6 to gear tcase adapter down the road. Any idea if the r150/tcase combo the same length as a w56/tcase?


MUCH Stronger. Variant of the 154 which you'll see in high-HP Supras. I'd personally just bite the bullet and do the 4-cyl tcase adapter - keeps you from having to mess with driveshafts twice, which should make it a wash. [/quote]

Did pick up some Downey swap mounts and some 4.3 swap headers (came out of a rolled runner with a 4.3) on the cheap though. Not sure if I'll use either one but figured I can resell and make $$ if I don't...


The mounts may work well. Play with them upside right and upside down for placement (assuming they are the poly bushing type). The largest issue I had with headers was the steering shaft. Couple of taps w/ a hammer provided necessary clearance when I did the 3.8 Buick... Decided to use Astro van tubular manifolds, modified with longer collector, when I did the 4.3. Either works well.
