Roller cam
I'm not the only guy who disagreed with you. I agree with some of it. There are far too many generalizations in your response, and some is subjective as well.
i had a 260/266 flat tappet cam( on a 107, in at 104) with 620 lift that PRH on the board here specced years ago.
Car went 10.38 best, typically 10.45/ 10.48. I raced it a lot, pretty much weekly. 128/129 mph.
A friend of mine, Scott Brown who knew my combo extremely well, suggested one of his cams( he owns a business that sells custom cams, still does)
He told me, let me design a cam for you, your car will pick up with it..
It was 258/269 620 lift on a 112. Installed per his instructions at 108.
Fastest the car ever went with that cam was 10.55. When you launched the car it felt like it had been given a shot of novacaine. Just numb, and lazy. Looking at the incrementals, it was off everywhere, but i will say the MPH was almost identical.
I changed nothing, except the camshaft and lifters.
This was a 416, 11.5 compression, W5 heads, 3350 pounds.
Nothing is 100% this or 100% that, but GENERALLY, a wide lsa cam shines with a power adder, also with real good heads, lots of compression, and or convertor.
As i mentioned earlier, class cars like stockers and super stockers most always run narrow LSA cams, because they are generally head limited by class rules..
Pro stock cars, on the other hand, have great heads, and shine with wider lsa stuff. Huge compression is used.
Always will find exceptions, but i stand by the above.
