I'd get their 67mm ball bearing turbo but yes, their turbos are made in the same plant now as a lot of other bigger name ones. On3 did have their "teething" issues getting off the ground but now they're established and the quality is up to par. I just hope they don't start charging as much as Hellion/BG in the next few years. They've done really great to bring the prices of these kits down.
There is always the option of a good used centrifugal supercharger kit as well if you decide you don't want to do a turbo. Cheaper, easier to install, easier to tune and will make more than enough power to split the block on a 302.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
