360 magnum with chevy roller rockers

I lost interest recently when I read that there a couple of you guys had minimal gains minimal gains for the expense...I read a dyno report on the conversion and the gains were only 12 horsepower...seems like a lot of expense and frigging for the gains[/QUOTE After you tap all the cheap gains and need a bit more I can see it,but most miss the good stuff and waste $$$ on things that do not show up on a time slip.
