Fair enough, but although going backwards you may still find it easier to rework the the solid mounts and use the shorter 2287’s.Morten and Mick said the BY2257 was the mount needed not the 2287. Anyhow I modified my mounts and we are in. The sad thing is since such time has passed and now Quaife' s are back available, I should have gone that direction and been patient. I would be near the same amount of money since I did not properly investigate the 365 transaxle I first bought vs the UN-1 I now have along with an ATB and one piece main shaft kit.
I just wish I could drop the engine 30mm to get the air cleaner down lower, I really wanted the 4bbl out of sight. I will pull off the intake next and have it milled level to get 15mill lower.
Your air cleaner sticks up above the carb a long way. Why not just get a drop base air cleaner. That will give you about 2". I have one on my 40. I will take a pic tomorrow. There is also an interesting video on Youtube about milling the central divider on Edelbrock inlet manifolds to make the normal manifold behave like the Air gap one.

I have a Holley 750 on a performer RPM Air gap intake with wedge plate and have no clearance issues, (not sure what you mean by out of sight though?)
You’re not the only one i know of to have made this mistake, one digit out on the part number makes a huge difference when it comes getting the engine in.
Not sure the ZFQ option would have been an easy change though, as that requires some significant changes to the rear of the chassis if it’s been built/ ordered for a UN-1.
Thanks Paul the B2287 are the 65mm high mounts but since I have cut and fit the chassis brackets for the others, the engine is as low as possible I believe with the UN-1 transaxle
