What cam would work best in my 2010 SG stock 96"motor? A 48H or 57H

The 48H max [email protected] rpm and the 57H 2200-5600rpm.

I want a cam that comes on reasonably early. The 57H seems to come on a bit earlier and go out a bit further at the same time.

What is it that I am missing here. If that is true why don't more use it over the 48H?

Hands down, Andrews 48.
Once tuned correctly, with a decent exhaust, those will show at/near 90 hp, and at/near 100 ft/lbs in a 96" on most any dyno, with quick torque delivery.
The 57's intake closing number dictates more compression to be effective, and to fully optimze, 10.25 cr is that number.

Yep, from what I have read, the 48H is the way to go for my 96". I have a Supertrapp Supermeg 2 into 1 and an SE air cleaner waiting to go on. I got a good deal kn the exhaust used.
I have read that that exhaust is pretty good. (I hope so)...
Any issues with cranking/startup with the 48H without compression releases?

Should fire right up.

I'd start with about 28-30 discs in the ST, when dyno tuning.
28-30 disks, wow it only comes with 20. I am not interested in top end HP I never rev beyond 4500ish and even that is very rare.
Why are you suggesting so many?
I am no pro but I have never heard of anyone running that many.

From working with Supertrapp exhaust systems for over 20 years on our dyno.

If the exhaust is plugged up, via not enough discs, the power will be 1) sub-standard, and 2) create unwanted heat.
Only alerting as to what dedicated dyno results have shown us.
Wouldn't that create "backpressure" that so many people think is cool? :devil

Back-pressure is a mis-used term.
0 back pressure is wanted, but controlling the exhaust pulse(s) is.
Supertrapp systems work very well, and while on the dyno, 3 plate increments are used to tune, and you continue to add plates until you start to see the bottom end torque move in the wrong direction.
At that point you back up 1 or 2 plates, and bingo....tuned.
