Problem with engine mounts?

I was contemplating purchasing a cowl induction kit to go along with the cowl hood that I already have on my '67. The engine always looked a bit off center. But when I started to see how the air cleaner lines up with hood, something is just not right. From passenger side fender to carb stud I have 24-1/2", from DS fender to stud, I have 26". Also when you place a straight edge on the air cleaner, there is about 1" below on passenger side fender, and about 1" above on the driver side. The mounts were both replaced with 2285 mounts. The engine frame brackets look right to the pictures shown in C.I. catalog (3955183 & 3955184), with the taller mount on the right. Is this nomal for this car? What could be the problem?

Re: Problem with engine mounts?

Unless someone in the past history of the car messed things up and just a guess, you may have BB Mounts in there. If so the car may originally have been a BB ride. I would also check if the Transmission mount isn't "off centered".

yeah, it may have originally had one of those pesky 427s in it. What are they called? COPOs or something like that?

You are describing exactly how a Big Block engine should sit in the car. However, the part numbers that you are giving are for frame brackets for a 67-68 small block car ! The part number 2285 is for '67/'68 302/350 engine mounts.

Re: Problem with engine mounts?

According to the pictures, I have small block mounts. The big block holes are drilled in a different location to move the mounts forward. Does anyone have any measurements for these mounts? I am wondering if 1 or both are from a different year/model car? There isn't by chance any spacers bolted under the mounts, that may be missing?

I am not sure what you mean by holes in a different location. On a first gen. camaro, they use the same mounting holes. The driver's side mount is taller than the passenger side, to obtain the engine offset. It is Exactly as you described in your first post. No, there are no spacers.

TJS69,

In the pictures you posted, take notice of where the mounting hole is located in reference to the center of where the rubber mount attaches.

Re: Problem with engine mounts?

What rubber mount ?

These are Frame Mounts... they bolt to your crossmember... metal to metal.



If You are talking where the engine mount center line is compared to the 3 mounting holes. The pictures are not taken directly perpindicular, so you can't go by the visual.

I'm thinking that 2285 mounts were the short ones that are used on Corvettes. Also I recall 2285 having a wider mouth that goes over the metal stands. 2267 is short and wide (not as wide as 2285 though) and 2289 is tall and skinny.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Re: Problem with engine mounts?

TJS, can you give me the measurements from the center of the bolt to the crossmember on each side?

Thanks, Jim

John,

The 2285's are for the 67/68's 302/350 engine mount. (8" Harmonic balancer)
The 2267's are the short and wide engine mounts for 67-69 307 and 327.
The 2283's are the tall and narrow engine mounts for a '69 302/350/396.

I have no idea what a 2289 is.

I am not sure what this dimension is. I can't get to it on my car.

They are all the same for a 67-69 Camaro. The frame stands actually hang over the main crossmember some.

The location of the center of the engine mount only varies about 1/8" among all the frame stands.

Re: Problem with engine mounts?

Look at the side profile of the mount. Draw a line across from each side of the base. Measure from the center of the hole to a 90 degree angle to the line. Is your engine out as indicated by your picture?

Re: Problem with engine mounts?

After re-examinling the mounts I have on, I remember that I first tried the the 2285 mounts. But found that it interfired with the mounting bracket for the short pump, power steering. As the bracket attaches to 2 of the motor mount bolts. I then had to go with the 2142 mount as it didn't have the secondary latch. However as both mounts are the same, the levelness of the engine should not change. So the problem remains the same.
