I've been kicking around using solid body mounts on my '67 project that I'm working on. The frame is narrowed 2" in the rear and has an HTH Truckarm kit and their front A-arms and disc brake conversion. I'm hoping the car will carve pretty good and was wondering how much solid body mounts would help. Is this waaaay overkill for a street car? Should I use Urethane mounts? Rubber ones? I'm not too worried about noisy urethane ones, or a stiffer ride with urethane or solids.
Looking for any insight that any of you guys may have. Who has used what, how well did they work etc.
Thanks in advance for any help/suggestions.

I would stick with either oem or poly i am running poly on mine i think solid is overkill unless you are racing

go solid. why screw around getting the suspension all optimized, and then allow the body to move around on the frame?
i can't see how solid mounts on a Chevelle would be any worse than any of the millions of unibody cars out there.
i do know the solid body mounts on my Nova didn't cause the car to vibrate too much- in fact, it felt a lot tighter with them in there.
i want to put solid body mounts in both my T type and 74 Monte Carlo.

novaderrik,
Did you buy your solid mounts for your nova, or did you make them? Either way, can you give me a little info on A)where to buy or B)how to make?
Thanks!

Poly mounts will basically give you most of the benefits of solid mounts without transmitting all the chassis vibrations into the cabin. Best of both worlds.

I personally, would go with poly.

It is WAY to much work to have these some-bitches made. Took me about 4 weeks to find a decent price. But then it only took a week to get 'em made. If you want some made, LMK, I can help 'ya out, to speed the process along..


Sorry for this crappy shot, it was the only one small enough to post, the others were 2272x1704 and I am too lazy to resize them right now.. ;)

i just ordered a set of Competition Engineering solid mounts from Jeg's for $35.
unfortunately, i don't know of anyone that makes solid mounts for a Chevelle.
but if you know of a good machinist, then i'm sure they would be easy enough to make.

Poly. I can't imagine the additional vibration and noise from solid mounts. May not matter on the track, but on the street it would suck.

I just wanted to thank everyone that has already replied to this thread. The info is greatly appreciated!
I'm still all ears if anyone else wants to chime in though!
Thanks again!

over the years- and yes, even back in the 60's- there were millions of unibody cars built. how much vibration gets into the driver's compartment on them? were all of those old Mopars vibrating death traps? how about a first gen Chevy 2 with a V8?
i know my Nova didn't have any sort of weird vibes due to the solid mounts- and in fact, felt a lot more solid and was more pleasant to drive after i put the mounts in.
if anything, i'd say a Chevelle would be a lot more pleasant inside with solid mounts than any of those cars, due to the beefy frame being solidly bolted to the body.

My 2 cents worth...I have to agree with the solid mount option for ultimate street performance situations. I've owned five Chevelles over the past 30 years. 4 were stock, but in the 1980's I ran a heavily modified 1966 Chevelle SS on the street. It had a twin turbocharged 427. I used a Dana 60 rear axle on springs, instead of the 4 link. Heck, this beast had a solid mounted ENGINE for pete's sake! I used a front cradle mount and a special mid motor mount bracket sandwiched between the engine block and tranny. That was solidly bolted to welded frame backets. Incidentally, there were no side motor mounts, the point being to minimize stress distortion on the block under hard acceleration (and believe me, with 28 pounds of boost the acceleration was...uh... hard :-)

Anyway, compared to my other chevelles, the solid mounted body / motor combination was NOT any rougher riding. True, the engine was carefully balanced, so it was not a vibrating nightmare either. On the whole, that car felt very sure, stable, and frankly a lot better handling than my other rubber mounted bodies. As I recall, I also added box sections to the mid frame rails to stiffen the frame.

So I have to agree...the vibration thing is overated, when compared to the benefits of a stiffer body/frame combination. Of course, it is not original, and would count points off on a concours restoration...but that's probably not what you're doing, right?

cheers!

Check these out.

LOL. I still have that same stock of aluminum sitting out in the garage. :D

Shovel, PM'ing you back next..
