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

Could pac1218 springs be ran with the sum-8707 ?

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.

Hello,

I'm am very interested in purchasing a summit cam. I'm stuck between the 8719 and the 8718.

I currently have an 04' LQ4 modified with flat top pistons. I have LS3/6 blue valve springs, LS7 lifters. Upgraded trunions. NNBS 5.3L intake manifold.

The motor is going into a 73 Scout II rock crawler. 42" tires, 5.13 gears with a 4:1 transfer cap and 4L60E tranny. I was wondering what summits thoughts were on what would work better for my set up. Thanks.

That is a conundrum. For wheeling, we'd lean toward the SUM-8718. It's closing the intake at 33 degrees instead of 36 and this will build more compression off idle for those points where you paused going up the trail. If you were doing dunes and could always keep the wheel speed up, we'd go with the SUM-8719.

I figured it would be a conundrum. This whole project has been one. But hey, what's one more on the list?

I've been trying to do some research on those specific things you mentioned above. And it led me to this website. A lot of great information on here!!

Anyway, as a rock crawler, I want to get my power and torque at the low end of the rpm range if possible. I also figure the less I'm pegging the throttle the less chance I have of breaking something.

I will try and find out more information on what cam to install but I'm leaning towards the 8718 due to the lower end operating range. I dont plan on doing too many high speed dune runs. I live close to the Rubicon, so slow moving crawling is what I usually do.

Thanks.

Just by looking at what it will be used for and the cam characteristics, "I" believe the 8718 will do everything you want. It will idle smooth at a low enough idle for rock crawling, which the 8719 will not, as it will have a slight lope at lower idle speeds. Just my .02....

Thank you for the response. I went ahead and purchased the 8718. They're on sale also! I like the lopy sound of the cam and it says it can be tuned to make it sound that way. So I think I can have the best of both worlds.

I don't think this engine will live in the higher rpm range under my usual driving conditions. Doesnt mean it wont get up there from time to time but if it does what I want under 4k rpm I'll be happy!

Thank you for your patronage. We think you'll be very pleased with the cam and look forward to hearing back from you on your impressions.

I've tried numerous cams on the market in various builds, all the FI cams from BTR, TexasSpeed, Tick, Speed Inc TU series, Comp turbo cams, so gonna give this Summit Pro LS turbo cam a try and see how it goes. Just looking at it cant beat it for the price and protected very well in shipping.

I'm slapping together a little LC9 for fun, got the SUM-8706 and SME-174003 to throw in it. I normally use the BTR spring kit, but hey I'll give these a try as with current sale they are a good bit cheaper. Also giving the Speedmaster studs another shot, I used some Chinese studs before and they had no issue holding 25+PSI with LS9 gaskets so not too bad for almost 75% off ARP price and stated as same material and very close in strength.

We think you will be pleasantly surprised with the cams. The SME-174300 spring kit is Made in the USA and is .050 out of bind at .600 lift-which does a nice job of damping them.

I'm looking at getting the Ghost cam for my turbo'd 5.3 build. I was looking on your website and trying to get more information about the cam kits that are available but when I click on the product the page I get forwarded to a page that say "Sorry, but there is no page that matches https://www.summitracing.com/parts/sum-8706-1 on the Summit Racing Equipment website"

Well, I guess we didn't do a good job of hiding our new Cam and spring kits, but our website should be updated over the weekend! So what's the cool new thing?

One question that comes up once in a while is "what springs match this cam?"....so we created matching Cam and Spring kits. But not just one, -we give you a variety of options to suit your budget. The Truck cams generally have a LS6 spring. The Stage .600 lift 1,2,3 cams (Turbo and NA) have the TFS-16918-16 Beehive and Dual Spring Kits as an option. .625 lift Stage 4 cams are locked into the Dual Springs- so no worries of coil bind issues. By the way, these dual springs are the new Nanopeened spring kits in Steel or Titanium retainer versions and a great value! Here's an example of what the webpage looks like:

For any cam part number, spring options are at a glance.

If you see SUM-8706, it's just the cam. If you see SUM-8706-1, that's the beehive spring addition. If you see SUM-8706-1DS, that's the Dual Spring Steel retainer bersion. SUM-8706-1DT is Dual Titanium. Also, you can click on the "Compare" box and hit the blue View compare button. That shows you the differences between the kits very clearly.

Thanks all and the update to the website should be done over the weekend.
