Hi There,

I am new to truck tinkering and am the proud owner of a 1954 Chevy 3100 truck. The engine in the truck was shot, so I purchased a good motor from a 1955 Chevy car.

I am looking for advice on the best way to mount the car engine to my truck. The truck engine mounts are on the front, but the car engine mounts are on the side. Is it better to use the current engine mounts and fit them to my truck or drill through the motor and make the car engine fit the truck mounts? Is there a better way?!

I appreciate the help.

Hi. best chassis mount kits i have found are from "chassis engineering" they have them for both boxed and unboxed frames weld in or bolt in, far as the 57 having side mounts? umm might be wrong but i thought chevy did front mounts on their V8s up through the 60s you might wanna run the numbers on that engine just to be sure what you have

Are you talking about a car six cylinder? If so the lip should be on the mount plate where the truck mount holes should be. Just drill some holes and make them square with a file.

What he said. Here's a tech tip regarding the components for front mounting:

And another for hole locations to drill the front plate:

Thanks for the replies...the car engine is a '55, 235. I will check out the links about drilling some holes.

Cheers,

You can also use the front plate from your bad engine unless you really don't want to tear either engine apart to make the transfer.

I had another buddy suggesting that too. Is there a lot involved with that?

58 car was first side mount engine
up to 57 6cyl had center front mount car and truck. 55 to 57 had 2 front mounts set at an angle on V8's. Been awhile since I really messed with alot of this on a regular basis but pretty sure I'm remembering correctly.

Also if I remember correctly 55 was first year for angled bell housing mounts. Vs' 54 back straight mounts.

1955-57 pass and truck mounted on the front side, not in the center front. 1958 pass mounted in the center side, trucks stayed front side through 59.
1954 was the first angle bellhousing mount in trucks.

Ruckin Chevy,
If I remember correctly from my 54 Chevy 3100, you have to remove the harmonic balancer, remove/lower the oilpan to access the two lower bolts for the timing cover, remove the timing cover, remove the camshaft thrust bearing (2 bolts), remove both timing gears (one on the crankshaft and one on the camshaft, and then you can remove the plate. It's your choice, but if you don't want to tear into the engine that much, drilling the two holes and making them square would do it, as Cletis said.
