My Cav has the 2.2L I4 OHV. They say it has the same lobe profiles as the SBC, so anyone who grinds SBC cams could regrind my cam. But since they can only remove material from the existing lobes, I have question how much of a difference they could make from the stock lobes. As you said, cam swaps take a lot of time and money, and I'm not sure I want to put that effort into a project with unknown results.
Advancing my cam will still take a lot of labor; Probably half that of a full swap. But the cost will be minimal, and I know it will move give the FE tuning I'm seeking. Moving the power band into a lower rpm range (via the cam advance) and going with higher gearing will probably be the best thing I can to with this engine/trannie combo.
But enough about my car. I can't wait to see the results if you do the rocker swap. Make sure you get us some good before/after numbers. With tables, and charts, and grapshs!
