Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION
Ok, I hate tests like this. It just fucks up everything. Why use a 104 LSA on a SBC? I have no idea. That head is good enough to use a 107-108 LSA. Of course, they didn't test THAT.
Second, the 104 LSA kicked the **** out of the other two for low end grunt, without giving up top end power. I thought that's what all you guys wanted...low end grunt.
Third, no where in that entire article is it said where each cam was installed. That is total bullshit. I'd have taken the 104 LSA and shoved it in at 100, or even 98*'s so 4-6* ahead. That would have helped the idle, because it shuts the INTAKE valve earlier and it would have moved peak torqu down a bit.
And still the 104 kicked the **** out of the other two cams, and it wasn't the right LSA for that engine.
For the final and last time, the LSA is a function of all the other camshaft properties. That test was at least misleading, if not an outright fraud. I say that because we all know that 104 is too tight for the engine, just like 114 is too damn wide. So was 110. I'd love to see the same test with every thing the same, and do it on a 107-108 LSA, a degree or two ahead for timing chain retard. That would have been the best.
And yet and still, the 104 kicked ***.
Damn.
