One of the tricks of mounting engines is having the right mount bolted to it. I have always shied away from ones that had a stud sticking down or the old biscuit, front mount-style that the small-block Chevys ran. The biscuit style would be OK now, if that was the period look I was going for, but the ones with the studs always end up creating a big boxy-looking mount coming from the frame.
I was taught that you should use a motor mount that allowed the use of a long bolt to secure each side. It is the simplest and cleanest way. These types of mounts are available for most engines. I have mounted all the small- and big-block Fords and Chevys and have always found mounts for them that allowed the use of a single bolt on each side.
The one I like to use the most is the small-block Chevy, non-locking type, motor mount. It was used on the '60s small-blocks and is very adaptable. The shape of its mounting points makes it easy to move around or remount. I have made plates in the past to offset the mount as it is bolted to the engine and move the engine forward. When the LS motors first came out, I used these mounts to bolt to the adapter plates I made to bolt to the LS engine. Now, thanks to Classic Performance Products, the average guy can install his LS just like a pro with their new Adjustable LS Motor Mount Plates.
Classic Performance has been filling its shelves with real cool stuff like these mounts for years. They have come up with quite a huge selection of chassis-related items for your build. Trucks and cars are covered, but trucks are where it started.
1. Classic Performance Products’ new Chevy LS motor mount kit. Now you can mount an LS engine in just about anything with the versatility afforded by these adjustable motor mount plates. They are available as just the plates, with rubber motor mounts or with the better poly mounts. The kits include everything to get you bolted up and ready to mount.
2. There are two lengths of adapter plates available. Since I’m going to use the shorter ones, I’ll bolt the longer ones on to show the difference and adjustability possibilities.
3. These two pictures show the length to which you can move the mounts on the longer adapter plates. With this kind of adjustment, you should be able to mount this engine in just about anything. Being able to move the placement of the mounts can help with steering clearance, header tube/collector issues on the driver side, and A/C compressors and starters on the passenger side.
4. To show you just how well these new motor mounts work, I just happen to have a '57 Chevy pickup that needs an LS engine. By the end of the day that engine and transmission will reside within those framerails, thanks to CPP's new LS motor mount kit and poly transmission mount. This beauty is out of a 2000 Firebird and came with the ideal oil pan. What luck!
5. This kit came with the polyurethane motor mount option so I assembled the mounts to the plates that can slide.
6. Then I slid the 1⁄2-inch carriage bolts through the slots in the mounting plate and bolted it to the side of the engine in the stock motor mount bolt holes. Now I have positioned the sliding plate and mount, and secured it with the 1⁄2-inch Nylock nuts. The range of adjustability is shorter with this smaller version mounting plate, but I'm just trying to hit a crossmember that is pretty close to start with.
7. The ability to move the passenger side motor mount to the rear will help with future connections to the A/C compressor.
