Chevy tranny adapter

I want to run a Chev 4L80 behind my BBF, what adapters are people using and do they work well.? I see alot of glides and 400s behind BBFs so there should be some good opinions out there! thanx for your help

what question do you have Bruno? Which brand of adapter are people using to adapt a chev trannny onto a BBF and do they work well?

i just bumped it for you in the "general section " to see if any one can help you out ....... i dont have a clue about your question

thanx

The biggest deal is the bolt pattern. If this GM trans has the standard chevy patten, an adapter plate will bolt the trans up. Next is a flexplate for the torque converter. You should be able to get one drilled for you. The last thing is the converter pilot. You will need the crank adapter or bushing to keep the TC centered. I build BBF-to-GM midplate adapters and could re-drill the flexplate if the holes will miss....UNLESS it needs to be SFI cert. Then you may need to call JW or somebody like that to get a new flexplate drilled to your pattern.

easy...just run a chevy motor

4l80s use the standard chev pattern. How well do the mid plates work and what issues may i run into

Are they the same bellhousing as a th400? JW makes an ultra bell for BBF to TH 350 and TH 400.

they have the same bellhousing as PG, t 350, t 400. i dont want to cut the bell housing, just looking for people who have used the mid plate type adapters and thier results. thanx

Another vote for the Ultra-bell...I have ran both, and cutting off the bell is the way to go. There really is nothing wrong with the adapter plate, the bell is just easier to deal with, especially if you are limited on room between the back of the block and the firewall. The studs sticking out off the adapter plate mean you need to have the tranny moved back an extra 2-3 inches before you can slide it forward.
Cutting off the bell is pretty straight-forward....cut it off even with the pump, bolt on the new one, and go. Another plus is the fact that you get built-in safety with the bell...no need for any external protection.

to bad they dont make a 4l80 ultra bell, i believe my only option is the adapter plate but want to make sure i am buying something that works. Thanx for the replies

why not a 4r100 or whatever ford called the electronicly controlled overdrive auto they put behind 460s in the 90's trucks?

or phone jw. if the ultrabell works on a th400 itll probably work on a 4l80e (the trans is an evolution of the 400) the jw tech department will be happy to talk to you.
