300 motor mounts for early mustang

Post #1 by yolocah » Thu Sep 05, 2019 11:09 pm

I've had this 66 coupe for to many yrs. with a couple of false starts . this time is different as I've already put a V8 suspension in the front end and a 9 inch ford axel under it with Mike Maier leaf springs on the way.
Now it is time for the engine swap from a 200 to a 300. I found one post " How to Install a 300 in a Mustang/Falcon" by nitrousnick.
It was a good start, are there other posts out there that deal with motor mounts/engine swap that I can't find in the archives.
Is there anyone making these motor mounts?
As always thanks for the help.

nitrousnick is the man when it comes to first gen Mustang / 300s. I did put one in a '64 Falcon Sprint but do not remember what I used for mounts. But if I were doing it today I would go with a universal "biscuit" type available from Speedway and others. Sometimes referred to as "flathead V8" mounts. Inexpensive and readily adaptable but requires custom mounting pads. ... ,1199.html

Can you weld?

It's super easy to copy the fancy pants mounts autofab sells that use leaf spring bushings. The motor mount dimensions for the engine side of the 300 are in the sticky thread.
1994 F150 4x4 8ft, engine is basically stock.

66" leafs, extended radius arms, lockers in both ends, nothing special.

:D Hi FTF those do look very familiar.Studebaker used a similar type in the early 50`s and later.The only difference is the Stude were a three piece.That is the two metal plates that had the mount studs were vulcanized to the rubber puck.
Good luck.Have fun.Be safe.
