LLSR L99 how high RPMs?
I'm getting ready to order most of my LLSR setup stuff on a stock bottomend L99. With my current setup I'm spinning it to 7250ish and crassing the 1/4 near 7350. Anyone know if it wiuld hold if I try to hit 75/7600? The cam was going to be a .680 lift but I'm thinking over .700, any idea or tips would be appreciated thanks.

Also stay under 700. lift springs get really pricey on LS3 heads, small spring pockets. Trust me! And if the heads aren't ported they STALL around 640-650 lift no need for lift past that with stock heads.

Kip specced a LLSR for me @ 243*/249* .670"/.640" 115* +3*
Goal Peak HP ~7000-7200 RPM, Shift 7500+ RPM with 8000 RPM
REDLINE.
Waiting on VARARAM INTAKE from Patrick also, any news?
MAMOFIED TFS LS3 Heads, Big Bore (4.175"), Stock Stroke, Long Rod
11.75:1 Compression.
I kept the lift below .700 because my heads stall at or just above
.700 and also for lower spring pressure and reliability.

EDIT: My C.R. is 11.4:1 and will be running on E85 if that even matters.

Don't know about how VVT affects REDLINE, but Kip told me for my build
8000 RPM is not an issue at all for his LLSR.
If I was using E85 I Would be using at least 12.75:1 compression
to take better advantage of the Anti Knock/Detonation
properties of the fuel.

Right now optimal shift points for me are right around 6800. That's right around where my power starts to plateau. I definitely need to figure out something intake wise. While doing some logging, I'm seeing around 95kpa at 4200 and up. There is some variance there, but the stock intake can't keep up right now.
