Motor Mounts

[Turtleman]

Currently swapping out the previous owners motor (68-72 sbc) with a 5.7 350.
Once it was out I see the previous owner made some engine mounts that set the motor so far back in the opening you couldn't get the distributor cap off. Now I'm wondering why someone would do that?, couldn't measure right, didn't know better,, who knows,,

So I have to ask, what's the issue with dropping the 5.7,sbc with a clutch fan in the so the distributor is off the firewall and sets back far enough to I have space behind the radiator?

Someone here's done it before, so can anyone recommend a/the correct motor mount to use?
