Yes, it would! They are designed to do is make that thing boogie. The Sum-8712 is the drop in version. We also have a towing version Sum-8718 if you were looking for ultimate torque for boats etc. . And if you dont mind swapping springs, the Sum-8719 is the .550 lift version that works with LS6 springs (sub $80) and that will extend the rpm range upward to keep it in the meat of the powerband longer.

The Pro Ls truck stage 3 Sum-8713 has been getting some good reviews. The lobes are more aggressive, but seat timing is nearly the same as the Stage 2 Sum-8701 and also benefits from the Ls6 spring swap

1218s would be a pretty good fit. Depending on the valvetrain mass and rpm you want to turn it, a 1219x spring shimmed .050 is an option. Wed want to see that on the Stage 3.

1219x could be used with Stage 4 as well with (.025 shim), but Tfs-2500286 and Tfs- 2500287 Pac duals would be preferred at that point.

Default Ls truck torque cam 205/217

Hi I am very interested in the 205/217 cam, currently have a 205/210 .550/526 115 (sdpc cam- cammotion grind) in my 03 suburban with doug thorley tri-y long tubes, jna catback, slp cai, self ported tb, pac beehive .600 springs.
I feel the 205/217 112 .500 will bring the torque in faster and hold power long with that cam. The 205/210 isnt a bad cam but not crazy about the 115 lsa, it power feels to come on after 2500-3000 and I would like something closer to off idle. I have always liked cams on tighter lsa's, esli;
I also have a set of slp 1.85 rockers laying around : I could use to bump up the .500 lift. Do you think this would hurt gain some power and torque? Wish this cam had a bit more lift say .525 or .550 but I understand why you guys have it ground with .500.
Thanks for anyhelp

Some of it depends on how much advance is ground into the cam and what the advertised duration is. Ours is 258/270 and I don't see Advertised listed on the SD cam you mentioned. You could virtually match our torque and idle quality by advancing your cam 4 degrees total. That exhaust opening isn't very consequential, but it would lose a bit by closing the exhaust valve earlier than what Cam Motion intended. I think our exhaust timing is a little more advantageous to holding on to power up top as it's ground, but probably offset by the lift as it's a drop-in cam. Your 1.85 rockers would come in handy, but you would need to make sure you have enough valve spring to offset the added rocker weight around redline.

See if you have a cam card for it. Cam Motion probably put a couple degrees of advance in it. If so, there are better places to spend money for the time being..

Is one of your turbo cams geared towards a rectangle port head? I'm putting together a LS3 turbo combo. It will be backed by a 80e with a 4k stall, 8.8 rear with 3.27 or 3.55 gears

Hello, we don't differentiate the valve events differently between rectangle and cathedral port. The LS3 specific naturally aspirated cams do have lobe offset to get more clearance with the LS3's true flat top pistons. With your converter, the SUM-8716 Turbo Stage 3 will be a nice fit. Specs are 231/234 115 L/S and +5 advance and .600/.575 lift.
