I just pulled a 307 from my '68 Elky getting ready to drop in my smokin 383 - woo hoo when I discovered the previous owner has bastardized (welded) the engine mounts . I don't trust these mounts and would like to replace them. What should I do?
The car was originally a 6cyl. You would think that chevy would have used the same cross member for 6cy & 8cy cars. Do you think if I grind these off, I can bolt on conventional mounts?
Yeah you should be able to grind it off and put on new boltable mounts, but my suggestion would be to use an aftermarket motor mount like a high energy absorbing polyurithane mount. Stops a lot of the everyday rattles you hear and are 5 times as strong as a regualr motor mount. Especially with the engine swap your about to do.
Thanks for the help!
Looks like I need new frame mounts. Where can I find them? Also, will 327 frame mounts work with a 350? (they did'nt make a 350 in 1968). Anyone have a picture of how the frame mounts are supposed to look for a 68 with a 350?
Those mounts are off of a later model...after 73. They are an improvement over the earlier mounts. I would go with them. If you want an extra safey factor, attach a short piece of chain from the motor to the frame on the drivers side.
Yes, 327s and 350s have the same mount locations.......
I found a picture of some later model mounts correctly installed. So here's the million dollar question:
Will these later model mounts install on my 1968 V6 frame to accept a 350?
Why wouldn't the 350 set down right where the mounts are at? The 307 and 350 are the same. You can always get a set of the old GM "quick fix" safety cables that were used in that era.
