UK Zilla may have something there on his post,I talked to Ron Hinson of Hinson Racing and I talked,begged and pleaded with him to make Hinson Basket's for the 87 lt500 and he started making them,of course after I had bought a new stock basket for my quad.If the LRD pipe made that much of a diff. on a mild modded engine what do you think it would do on a full drag engine?As far as peak power @ 6000 rpm's,Vito mentioned that to me when I was talking pipe's with him,and he said that it was because of the bore and stroke size,mainly the stroke.
