hey guys im going from sbc to bbc in my 66 chevelle, lemons say they build their bbc headers based on sbc engine stands and moroso engine mounts. what is the difference between sbc & bbc stands? height maybe? im thinking if it is height they will give me more room under oil pan for steering linkage clearance

The sbc mounts are offset farther from the firewall than the bbc ones...

I'm pretty sure the lemmons will have issues with the steering shaft if you don't run the correct frame mounts. I ran a bbc in a 67 'bu with the sbc frame mounts and had no issues with the rad using a short water pump set up and off the shelf headers, but the tubes were not as big as the lemmons. THe lemmons tube size and routing limits you to pretty much using the mounts they call for as the clearances are pretty close from what I've seen. Never owned any, just looked at a few...
