RE: blower whine, it really isn't all that important to me, I just liked the sound of the gear drives...but if they are not worth it I'll just forget it. Don't need to trash a near new engine.way before it's time...
And Black Mountain belt drives are way pricey... for what I'd need, a PS and A/C pulley also I'd have about $425 wrapped up in billet parts plus would probably have to have some new PS,A/C mounts made...for some reason bolt-ons never are ...LOL
