LT4 Vs. LS9

[colorado80439]

I've toying with the idea of doing 1st gen Camaro build with Detroit speed subframe etc with either an LT4 or LS9. I'm trying to gather facts of fitment issues between the 2 engines such as hood modifications, fuel delivery, power steering pump, vacuum boosters, supercharger cooling, front drive systems, headers, electrical and probably a long list of things that you don't see until you get there. Also would consider an LS3 with low profile supercharger to avoid hood fitment issues. Let me know if you would share your experience with these secondary fitment issues
Thanks
