Hi Craig
I have same imported LS1 as you and mounted a Holden alt. down low to get it out of the way. I machined up barckets in alu. which wasnt much hassle and I think would give you plenty of room for the h/dryer. Look in my gallery for a pic of the alt. I just posted. or try clicking link below (not sure if it will work as dont know how to add link to a thread??
