Tell us more about the adapter that will fit the 2F bell housing to the r2.8....I have been looking at doing conversions for a long time and was going to stroke a Chevy 350 and go with the propeller mounts, but met someone in Portland, OR that put a Chevy 400 in his FJ40 putting out 400 HP and broke 3 transfer cases. I have been looking for alternatives to keep the 2F bell housing.
Now that the Cummins R2.8 is available and the aftermarket is providing support for this engine in the FJ40 I have found an adapter that will fit up the R2.8 with my 2F bell housing. I will use the bell housing to locate the drive train forward and aft in the frame. I plan to use the H55F transmission and a split transfer case and if I still need a support for the transmission so be it.
