hey im looking into the lumpy cams for the holden 202's and wondering how much it is to get done and what it increases
it doesnt increase shit until you get everything working right.
cost is 130 for cam and lifters and is a complete waste of time till you get a decent exhaust and ignition system. maybe even diff gears and a stall converter, depends on how "lumpy" you wanna go.
i agree you need to do more than just the cam, or it will do nothing but idle lumpy.
a big duration cam or 'lumpy' cam, as pointed out will probably make your car slower than it is, if it's not combined with the right engine mods eg compression, exhaust etc
you could go with a mild cam on a stock or near stock engine and pick up some performance if you choose the right cam.
