280ZX vs 300ZX engine bay

Taking a look at some of the hybrid SBC swaps done with 280ZX's and Z31 300ZX's, it looks like the 280ZX's have a longer but slightly narrower engine bay, making the headers a tight fit but giving plenty of room lengthwise.

While the 300ZX Z31's have a wider bay that is easier on the headers while getting kinda snug with a SBC.

 

How well do said engine bays stack up for a SBC / LS swap? Clearances for headers and the front end accessories?

 

I've been doing the run around with California smog info, trying to see what would fit better.

Anyone have any figures that might help? Rough ones, anything. Rather not PM eveyone that has done the swap to try and get some dimensions :)

 

Firewall to radiator? And how much room you have between the front end bits and the fan?

 

Header clearance? Custom, block hugger, rear exit?
