What I'm considering is using an old cathedral truck intake for a build, and using a 13-14 GT500 injector like seen here (https://injector-rehab.com/shop/Bosc...for-GT500.html). The information i'm using on the GM truck injectors is here (https://www.lsxmag.com/tech-stories/...oss-reference/).

From looking at the o-ring to o-ring specs, they appear about the same height, which wouldn't require spacing the fuel rail or anything like that.

Or am I looking at the wrong spec ?
