The Ultrabell is SFI approved. I bought one years ago but have yet to install it. Maybe it'll go on the Imperial.

Same here, got mine during that group-buy that happened on here a few years ago! The Ultrabell is SFI approved. I bought one years ago but have yet to install it. Maybe it'll go on the Imperial.

Sounds like he's going to weld a B/RB bellhousing onto a 518 You may consider using a A618/47RH. It can handle more power than the A518. I would assume you could weld on the ultrabell since it to is aluminum(along with the bolts). I believe the pump bolt pattern is the same between the 518 and 47 so the ultrabell would be an easier install. I see they make a adapter plate to install a ZF8 to a big block, That would be even better than any 518/47rh but would need a controller to run it. link

Wouldn't a gear vendors OD be a better route???? it could be. however, i priced out a JW Ultra bell [big block], a rebuild kit for the A518, a valvebody kit, and billet servo kits, and it came in roughly $1000.00 cheaper than a gear vendors unit. i did not include any driveshaft work because one would be doing it [shortening or replacing the driveshaft] regardless of which way one went. i also didn't include a converter, because of so many choices one could make. the A518 also has a more favorable [in my opinion] overdrive ratio at .68 than the gear vendor's .072. it [the A158] is also a shorter package overall, unless you have a "shorty" 727 to start with. the A518 may require some tunnel mods, but the gear vendors may, or may not require some as well. remember, this is just my opinion/observation. your mileage will vary.
