it can work just fine, you need to space the mount forward, I have used original ford front shackle links as spacers, and a small body fuel pump. Both summit and speedway sell one. This will only work in model A up to 34 frame. 35 to 40 frames the fuel pump slams into the front cross member a lot of the time. you just need to get a Hurst style mount and start mocking it up till you get the right combination.
You can make a 1/2" spacer to put between mount and block that will help with size of relief. The Wizzard
So how does a 1/2" spacer effect firewall clearance if using the Hurst mount on the stock Ford flathead front mount location?
It doesn't. The Hurst mount is slotted for the Biscuit bolts. The block still bolts to the Trans in the same way and the motor sits in the same exact spot. Just the cradle moves forward and effects nothing else. The Wizzard
It will work, but it's tight. I did it on my A after looking at the pics of the Rand Man A coupe. There is a build thread on here that shows how much material is removed from the back of the frame mount. I also moved the frame mount closer to the front crossmember. Look at the pics in "A Full Fendered Side Project" posted by Ryan, page 12.
