Default Rubber or solid motor mounts for TT car?

When I put the motor in my '81 Corvette TT project, I used new replacement motor mounts but I've been thinking about going the solid route. This will be 90% streetcar. What are most using in this application? The motor is a 383 efi on E85 with twin 57mm BWs. I'm basically done except for fabbing the down pipes and completing the exhaust. So... solid or rubber motor mounts?

I am using tall moroso solid big block motor mounts but I don't have it all together yet so can't really tell you. However, that is what was recommended to me. Solid engine mounts and a poly trans mount.

I'm leaning more toward the solid mounts now that I've seen a couple of YouTube videos and how turbo motors really torque up in these cars. I guess vibration isn't an issue?

I run solid mounts with solid mount trans plate and poly tranny mount. Yeah there is some vibration but nothing major. Street/ strip 8.50 car.

I've run rubber mount with an engine strap with good luck. Also poly engine mounts aren't bad either.

I use motor plates in my street strip setup and i dont think it vibrates/shakes very much at all.

Id go solid, rather live with a little annoying vib than breaking a mount
