I have what I believe is an original 67' 427 side oiler block. I am trying to mount it now and I have run into difficulties. The reproduction motor mounts for a "390-427-428" did not work. The passenger side insulator that bolts to the block needed to be modified due to slightly different bolt spacing on that side (off by about 3/8"). It looks like there is an
oil gallery there which is why the bolts may be moved up but the lack of symmetry has me puzzled.
Then I ordered what was advertised as Factory Ford motor mounts for a "390-427-428" off of EBAY. I paid a pretty penny for them and they had the same situation.
Does this sound right ?
Also, as far as clearance go, it looks I have about 3/16" between headers and shok tower. Is this too tight ?
Thanks in advance.
