Anyone running this type of setup on their sbf 302/347’s? I’m having belt slippage bad on my 347 that we converted to Serpentine belt from 1990 LTD. I’m only running polished summit 100amp 1 wire alternator, edelbrock victor jr aluminum water pump and crank. I have alternator as tight as I can get it and still squeals and eventually snaps belt. Also for people running serpentine kits or even this Gilmer style, I’ve noticed some kits come with a threaded double eye bolt for bottom alternator rather than flimsy regular brackets, does this make a big difference? I’m open to ideas on adding a idler pulley and a tensioner pulley to setup to help stop slippage, what tensioner did you guys pull from (what’s the part #?) thanks for help guys. I really like the Gilmer pulley kit and price is right if I can make work.
