What I did, no more vibration than with both rubber but the eng barely moves when you get on it as seen by me with the hood off.

It's a real tight squeeze, but I managed it for a few years. I couldn't crawl completely under, but just enough to reach most of the engine parts. Lots of times I had to exhale to slide in. I don't know if I could still do it because I've put on a lot of weight, but I can still snake my arms far enough under to reach the oil plug.

I am glad I didn't put the hood back on before I went for my first test ride with the new top end installed. The motor was torquing up on the drivers side a good couple of inches...time for new motor mounts here...I guess I am stuck on the same question, poly? or solid?

When I built the motor for my 70Z28 I put in new stock motor mounts and the one on the drivers side lasted about 2 months. I switched to Moroso solid mounts (because of necessity) on the engine and a polymount on the tranny. No more problems.

Any noise or vibration? Seems no one gets noise or vibration.

I bought a rubber mount at NAPA to replace the passenger side mount (I think it was the passenger side). It was the 3rd mount that I had purchased, the ones from AutoZone and O'Reilly looked like the original but didn't fit. The NAPA mount fit but looked totally different. Either way, no more fan rubbing the radiator shroud.
FWIW I didn't loosen the distro cap or the exhaust.

I just replaced mine to solids, broke the rubbers right away with the new 383. Huge difference is response and feel. Adds another exclamation mark to the already wow Weee!!!!!!!!

I'm glad to see you guys aren't a bunch of sissys wanting to make a luxury car out of a C3!
Seriously, solids are the way to go. Just like an aluminum radiator; do it once and forget it!
