My FFR Roadster was originally set up for a BPE 347, I have an opportunity to purchase a BPE 427, but I need to know if the motor mounts are the same or different and are there any other structural items that are different between the 2 when FFR fabricates the frame/kit?
If they are different what is the part number for the 427 motor mounts?
Thank you.

They are the same. FYI, the BPE 427 is still a small block Windsor derived from the taller deck 351.

Thanks, I suspected as much, are there any differences in the manufacturing of the frame/kit between the smaller 347 vs. the 427? The reason I'm asking is I'm just trying to make sure before I jump in I'm aware of all the changes I have to accommodate for. Thank you (again) by the way for the info.

No chassis differences however if you bought headers through FFR they are different.

Motor mounts will have to be notched for a Dart block as well. Not a big deal, just an FYI.
