Dual, he can, thats why I mentioned the adjustable cam gears.
And Guy, if you look at the lift/ duration cut on an LS cam versus a SBC cam, comparable engine builds are WAY off. Thats why I thought the LSA might be different.

Mmmm not from what I've experienced. My can(race motor) is the same as what would be ran in an ls1. Efficient heads, 347 cubic inch, etc.

I don't have to. Ben's car has nearly identical can specs from what I recall. And the potential for his motor is the same as the potential for mine. Similar bore, stroke, compression etc why would the brand of v8 make a difference?

You dont have to, but youre wrong. LS cams have way more lift and way less duration than comparable SBC cams. Why? I dont know. Ask Glenn

40 Year old tech compared to what? Compare a new relevant custom grind for any motor and you'l see what I mean. Sure I can find some OLD stuff and use it for the argument but plain and simple what is in a catalog and what will be ground from a good grinder is different. Off the shelf cam specs don't take into account which heads you use and what kind of work they have. A sbc and a sbf are not much different and yet why is the new tech for sbf motors so limilar to the lsx stuff?

*IF* there was any reason as to why there is a difference with lift vs duration is the LS heads are more capable of the higher ramp rates than SBC heads. But that's crap because any decent grinder will grind almost identical cams for what they are. My motor .600/.589 234/244 113 is a common ls1 grind. My grinder was very clear I needed good valve springs and pushrods to run a cam like that. Don't need to go all out on an lsx like you do a sbf or sbc

Roller vs Flat tapped....Roller has MUCH more aggressive ramps.
