Yup and they will normally have 9.005" stamped in its place. Unless they decked it to some weird number or true zero.

 

Makes perfect sense, that must be where it says T0304EI and I think 188169. Used those numbers to ID the block last summer and they stuck with me. I feel better about my assumption now.

 

Got the new motor mounts today. Nice little surprise when the mailman delivered them too! The box had a hole in the corner and apparently the Snap on ratchet was loose in the mail somewhere between Iowa and my house so the USPS assumed it fell outta the box with the mounts (hole in corner) so they delivered it to me! Thank you very much.

 

Solid motor mounts? Let me know how you like it. I had solids on mine, and didn't care for all the vibrations (as if my car doesn't vibrate enough)!
I put urethane mounts in their place, since they're interlocked and can't come apart anyway, and they give less vibes.

 

I'm a fan of solid mounts myself, but they do transfer every vibration of each piston firing. More so at idle than as the engine smooths out at higher rpm's. I ran them on my '71 until a couple years ago when I wanted to "tame" the feel and went to poly mounts. Still run them on the Austin, and just did solids on the Falcon's 454.

 

I don't have an opinion either way but I guess poly is always an option later on if need be. Not too worried about it at this point but good to know. These mounts are definitely better than what just got taken outta there. Did you guys have any problems with things vibrating loose? Guess there's always that possibility with or without solid mounts. I just wanted something better than stock mounts.

 

Just my teeth, mostly.

 

I have solid mounts. I like the fact the whole car twists when I wrapped it up. I dont know about vibration. I had them in my Nova but that didnt have interior and when it did have exhaust it was 3" straight pipe bolted directly to sheetmetal with no interior and a cage. The vibration my my vision blurry at the start of my run.

I just laid down 400 bucks worth of sound deadner to help with the noise. I'll report back but right now I'm skeptical because it stills sounds like a drum with .100" of rubber sprayed in it.

 

I just read an article about a strange problem that is possible especially with solid motor mounts. It seems that Holley carbs, double pumpers in particular were almost impossible to get the AFR right at a cruise RPM on a dyno or a car with solid mounts. The added vibration was causing the rubber check valve in the accelerator pump resonate to act as a pump and was dumping fuel from the squirters even at a steady idle. I don't know what carb you're going to run but it's something to keep in mind. The most reliable fix was to change to the older bowls with the check ball rather than the rubber check valve. It was on Hotrodders.com. I'm thinking 700 dp so I'll be going poly or stock.

That being said, great deal on the ratchet!!! Wish I could find a deal like that!!!

 

I check bolts pretty regularly on my Austin, as the stiff suspension will work things loose, even if I had rubber motor mounts. I don't seem to have any issues with parts falling off, or working loose, and I put about 6,000 miles on it last year.
