Stroker specific cams?

It's all dependent on the combo. I've played with desktop dyno for years. I know there are some who think it's bullshit, but the better info you put in, the better the info that comes out. And without fail, on certain combos, especially mild builds, a wide LSA wins out every single time below 5000 RPM and that's where 90% or more of a street engine's time is spent. Yes, it's not as much of a peak torque number, but it's a flatter curve with more available torque, for a longer time, in some cases a lot longer time.

As I and many others including yourself have said many times and it falls upon deaf ears with all the "gurus" it all depends on what you're doing. My rule has always been look at all the factory high performance engines. Except for VERY few exceptions, the camshafts were ground on wide LSAs like 113-116 AND THEY WORKED and worked very well. Most times for a street car, the farther away you get from that recipe, the worse of a "street car" you end up with.

But of course, like I said, you caint tell all that to people who've done it all and know it all.


There's a difference between DDD, a real dyno and time slips.

I'm not the only one saying it. David Vizard his literally hundreds of tests where the narrow LSA was a better.

Again, so I'm not misquoted, LSA is the RESULT of the timing events. Period. You don't call and ask for a 105 LSA. You let the events dictate where the LSA falls, within reason.

When I see these wide LSA cams for low performance, or induction limited stuff I know, for a FACT, the timing events are wrong. Fix that, the LSA will fall in line and the engine will make more power, everywhere, except it won't have as much after peak RPM, as in over-rev. But most guys don't like to RPM their engines, so that should be no issue.
