FWIW, your TBI V6 cam for the 1.5 rockers can be used in your Magnum engine and have increased lift and .050 duration with the 1.6 Magnum rocker ratio. It's a good upgrade and still plays well with the Magnum electronics. Shortening the runners in the "kegger" intake helps, too.
How do the stock '88-'89 TBI V8 cams (roller correct?) w/1.5 rockers work in the later '93 up magnum w/1.6 ratio rockers? Are they spec'd w/slight increased lift and duration as well?
