Great Quality Engine Mounts

October 09, 2014
I purchased a pair of these engine mounts for my 1931 Ford 5-Window Coupe that I will be using a Chevy 327 engine in. They are great quality mounts and using my 211 Amp mig welder they were a breeze to fabricate. It took me an hour for setting them up in the right place and tacking them so I could check fitment. And a few minutes later they were in place forever, great mounts I would recommend them to anyone that is building a hot rod / rat rod. And the folks at Speedway Motors will sell them to you right. Thanks and Safe Motoring, Torque
Yes, I recommend this product.

I had to modify them be get them to fit right for my application (23 T-Bucket) but that was because of the way I wanted to install them. They are made well enough for you to cut and re-weld if needed.
