Make as much as you can yourself. Like engine mounts for one thing. Adapter mounts that use the factory k member perches end up shooting you in the foot for using car front covers that not only look better but keep a lower cog. I plan to get the oil pan and headers I'm going to use and then fit the car around that. Nothing pisses me off more than buying a bunch of "adapters" and then doing a ton of fabricating anyway. Did a bunch of that during the BB swap days. So I'm just going to fab it all out of the gate.
