Takes a little work to do it right. First, you need a good quality engine mount (3/4" forward position) and if running tall valve covers, you end up needing to notch the firewall with a pocket kit in to provide the needed clearance at the back. Next you need a good set of headers to squeeze in, and that usually means some mods with your steering box assembly. Some run a rack and pinion, others build custom headers and fit them around a 605 steering box. Finally, you need a really good radiator to keep them running cool.

I've done it before, and now it looks like I'm about to do it again.
