Zoom is an OLD name that disappeared it seems for awhile and popped back up; this makes me nervous when new companies bank on nostalgia to sell a product. Thats my personal opinion and no one elses.
My Dad has a Zoom lightweight flywheel from about 1968 or so....it was finely crafted back then.
Ive only used McLeod, Hays and Centerforce. I had a litany of probs with the C'Force and the Hays was an OEM replacement I think in a ford ranger. It worked fine. So if it was me I'd pick McLeod.
Flywheel is going to depend on your bellhousing to a great degree. I wouldn't use an OEM flywheel. I'd prefer something steel and perhaps SFI
