I originally had C2SE-C 406 tripower heads on my Shelby. Yes, they fit. The two center lower bolts cause one to use almost every word of the four letter variety many times over as you work to get them tight.

I didn't think it was possible to get them? I believe that the 67 427 Fairlane had holes drilled in it to reach those bolts and plugs put in the holes?

Ok I am a little slow tonight, how can I bolt in a 63 427 engine that has 2 holes for engine mounts in a mid 60s Mustang that uses different frame mounts, that wouldn't require an engineering degree to figure out? ;D

Maybe if I can get this early 427 conundrum figured out I can put my 62 406 W/ 428 crank= 428ci to good use in something. :)

Anyone install an early 2 bolt engine mount FE engine, in a mid to late 60s Mustang?  :-\

Doug, I don't think you could use any cast iron exhaust manifolds with them, but with the headers you can get to the vertical pattern bolts with different 3/8" wrenches. The 6114 Hookers on my vehicle allow relatively easy access to the end lower locations. However, the reason for my change post the rebuild was to make access slightly easier. There are still a couple positions that are very difficult to get started. They are the ones to the rear side of the tubing. Hooker didn't dimple the header enough to start them easily.

Yes, you can also use the two bolt block mount. One bolt is where it belongs, the other has to be drilled.

Keith- I can purchase the 2 bolt engine mounts most everywhere, the problem is the frame mounts... and trying to drill the frame mounts to get the stud located in the engine mount to drop in a properly located hole in the frame mounts. The 65 and newer motor mounts did not have a stud system so to speak. :-\

It's because you use the mustang block plate, it just requires one hole to be drilled in the plate.  The other is in the correct position. You no longer use three bolts like the 65-up blocks. Many a 427 two bolt blocks are in mustangs.

So what parts are recommended?  A gt- 390 Cougar, Fairlane set of engine mounts modified to fit frame mounts. I am trying to avoid drilling a hole in frame mount where stud of standard old 390 mounts would allow engine to sit improperly in engine bay.

Ok Thanks for the answer... Let me go the other way has any one used an early Fe, in a newer Mustang chassis using the old original engine mounts on the block, and then what modifications are needed to adapt to the frame mounts? :(

     I put a '63 low riser in a '69 Mustang ( 390 originally)  and only used two bolts . Never had an issue.

You use EVERYTHING that is currently used to mount the FE into the mustang. The only changes are one hole in the block plate that the rubber insulator bolts to. Otherwise there are no changes. I know MANY who have used the earlier two bolt blocks.

+1  Drill one hole and bolt the plate on the block . No problem after that except the damn header bolts ARG.

QuoteAnother question is can an early 63 427 block, motor mounts be drilled from the 2 holes to the more common 3 hole motor mounts of later FE blocks?

QuoteNo, the cast bosses needed on the side of the the block are not present to do such properly.     :(

     Scott.

    I feel the above statement is correct, as the inquiry was of an "early '63 block", but note there are some '64 FE blocks with the cast bosses for the later 3-bolt mounts (blocks are actually most often machined with a total of four bolt holes), but only drilled & tapped for the earlier two bolt configuration.

    I realize this may not be directly relevant to the original inquiry, but I felt perhaps it may prove so in a future review.    :-\

Scott- I have a 62- 406 and an early 63-427 I want to put to good use in a Mustang application. These are 2 bolt cast in holes for engine mounts, the question is what mounts for both the frame and the engine are used. Answer seems to be purchase a later set of engine mounts drill the mounts using only two of the bolt holes and everything will work out. Whew hope it works thanks to all that have helped out here.
