Re: th400 ?

2 ton is dead on right, hhowever, there's some variables here...
Yes, you already have a high hump
Yes, a TH400 goes under a low hump 9GM did millions like that)
However, the variable in the off band engine will be in the height of the mounts.
Either way, you already have a high hump so patch the hole from the shifter and call it good.
