I need some advice please.

I am putting my motor/trans combo back into my 69. The car had been PowerGlide equipped which I swapped to a Muncie-20 that I recently rebuilt. During this process I pulled the entire front end off of the car and replaced the heater blower, repaired/replaced the sub frame bushings and repainted/detailed the firewall and sub frame. Iíve also replaced the master cylinder, brake lines and wiring.

I picked up new GM motor mounts and installed them onto the motor. One of the old ones was cracked. In order to get the motor mount bolts through the holes I had to loosen all the bolts on both sides of he cross member to frame mounts and even with that I still had to beat the second motor mount bolt through with a hammer. Iíve yet to try and tighten the six bolts on the cross member but can tell that the rubber in the mount will be under quite a bit of tension once they are all drawn up snug. Is this normal or should I have approached this in a different manner.

Thanks for any advice!

I believe the small blocks had a couple of different mounts, one for the 350 (and maybe the 302's) and the 307 mount which is different. It's possible that your mounts aren't correct.

You shouldn't have to beat them and loosen the frame to stand bolts to get them in. I'd take a hard look at the mounts and compare them to another set.

Check my suspension page, there is motor mount info in the Engine section.

Compare your old mounts to the new ones. There are two heights of frame brackets, and two thickness of engine mounts.

Low perf engines in 69 used thin motor mounts, and taller frame mounts than the high perf engines like the 350 and 302.

Thanks guys!

I'm heading over to the garage now and will take along the info provided and see if I can figure this out.

Note to David: Your website is terrific!! What a great resource!! Also, I tried to sign the guest book on your site but was not able to access the page. I kept receiving an error message on that link.

Note to Camcojb: What a great looking 69!! The rest of your stable of steeds are also unbeleivable!! If you find that you need some extra room to store any of them I'm offering a warm, dry, lovely space or two next to my 69 back here in good old PA Dutch country, home of the Amish

My web counters and guest page are provided by "Beeseen" They don't seem to be "up" anymore?
Don't know what is going on with them!
Thanks, David

When I replaced my motor mounts, the holes weren't cleanly lined up. I had to take my die grinder and oval them. I found this out because I was having trouble, also, getting the bolt in.
