LY6 Cam Selection Hello!
Trying to figure out some good options for a cam in an LY6. I ordered a VVT delete kit. I was looking at the popular Sloppy Stage 2. The engine is going in a 05 RCSB Colorado with a 4l80e. Plan is a streetable truck that will see the track. Good chance for boost in the future, but not for the first year. Any suggestions? What's a good spring kit to go along with it. Thanks.

Our Pro LS stage 2 turbo cam p/n SUM-8706 is a new and improved version of the Sloppy stage 2. The valve events are similar, but the lobes are Much better. Grind quality is outstanding and we've priced it right inline with the Sloppy 2.
We designed it with a bit more lift at .600/.575 lift to work with today's common, affordable and quality .600 spring packs like the TFS-2500286 or 287. We can't talk specs now, but look for an announcement on or before Oct. 10 and we'll have another option for you that may be even more suitable.

TFS-2500286 springs are Pacaloy Dual with 160 @ 1.800 installed heigh, 395 @ .600 lift, 405 @ .625, max lift of .660 in (coil bind at 1.050). Open pressure isn't so high that it's going to wear out parts, but it has the seat pressure to do the job as you progress.
As for lifters, everyone loves our LS7 spec lifters. P/N for lifter/trays/bolts is SUM-HTLSKIT

Interestingly, turbo cams and truck cams share some of the same characteristics- but for different reasons. SUM-8706 would be a good naturally aspirated truck cam as long as you're running a 2800+ converter. If you advanced it just 1 degree, it would match the intake events of our SUM-8714 Stage 4 truck cam and each of the exhaust opening/closing events would be 2 degrees earlier (not a lot of consequence there). You're gaining another .055 worth of lift though so you'll have comparable numbers power wise. With a decent converter, you'll have a mean machine. You could install it straight up and smooth the idle a bit. If that's still just one step bigger than what you intended, I think you'll like our next announcement.

Perfect. Basically my goal is to get a cam in their that will make "big" power for a stock N/A pump gas engine, but something that will work well for boost in the future. The truck won't be pulling trailers or anything like that and in stock configuration weighs 3100 lbs, I just plan to drive it on the street occasionally, not a daily driver. This cam and spring set sounds like a good option for me. I plan to keep the compression stock for the time being as well. What do you recommend for a valve compressor tool? Will that combination work with the stock rockers and push rods as well? I'll start looking into converters as well. I don't think it's too big like you're wondering but this is my first venture into the LS type engines so I'm still learning. Thanks for the help thus far.
You didn't mention the year of the LY6, but the 2007-08 injector p/n 12580681 were 30 lbs which are going to be marginal at as little as 400whp . The 09-10 injector p/n 12587269 were 40lb and support roughly 525whp. Let us know if you need anything else.
