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

tough motor mounts

September 04, 2013
I put a set of these in to hold my 383 stroker after i tore up 2 sets of stock style mounts. These have been rock solid, just enough cushion to kill any idle shake in the motor. Which with the 7\4 swap and huge cam, isnt much but its allot less then the stocker ones. Should've done these the first time.

Sturdy, easy to use motor mounts.

September 03, 2013
Bought these to install a Chevy 350 in my 1963 Ford F100. Easy to modify to allow perfect positioning of the engine. Once installed they are sturdy and allows for easy removal and reinstall of the engine. Kit could be enhanced with templates of cardboard to speed up the fitting process, I made my own templates and used them to cut the brackets for final installation. Easy enough but if included one would not have to spend time on finding a piece of sturdy cardboard.
Pros:
  • easy to use. sturdy design.
Cons:
  • no templates included
Yes, I recommend this product.

SBC swapped into a 54 Chry New Yorker!

December 16, 2010
Had to cut down frame brackets to fit-but was easy to do. Welded nice and is strong. I am swapping a SBC into a 1954 Chrysler New Yorker which is not an easy task to say the least. I am doing it while keeping stock steering and suspension. Will buy these again!
Pros:
  • Fitment
  • Ease of Use
Yes, I recommend this product.
