4.8 swapping my 99 k2500 suburban and wanted to do a can upgrade while I was at it. This cam is priced well and looks promising. Advertises a operation range of 1500-5000rpm. It says its for the 4.8 but I know the stock 4.8 cam makes power to about 52-5500rpm. I don't want to sell the 4.8 short in rpm. I do have a 4:10 gear and she runs about 3000 at 75mph. Specs say 212/218 and .522/.529. Didn't know if anyone had experience with this can or not. Thanks in advance.

212/218 is a VERY common spec, and your lift is mild. You don't show the LSA, but if it's in the 113-115deg. range it should run pretty well. It is run in everything from 4.8 thru 6.0 or more. A VERY versatile cam! VERY flexible.
Make sure to run enough valve spring for the lift. LS2 or LS6 stock springs will be plenty.

It is cheap, but you are missing out on ALOT of power potential with such a small lift even on a 4.8l. The tsp stg2 low or high lift will make more power everywhere. Do it once and do it right. No need to lose out over a saving money for a little bit longer.

After listening to the video above, I am surprised it idles that unevenly for such a mild cam with that LSA. I think it needs tuning BADLY.

i was looking at cam motions stage 2 truck cam at first, might end up going that way regardless, the melling cam is just soo cheap and tempting. read about a guy picking up really good power with just that cam, also saw a dyno test were a 4.8 made 382hp and 359tq at the crank with a xr265hr comp cam the same "advertised" spec's as this melling stick. i know valve timing events could be different witch has be worried on what this cam can or cant do, hence this thread. i cant find any dyno results for this cam on the web and very little info about it period. regardless of cam choice, i would like a noticeable idle but would rather it perform well then sound it and not back it up. not that this is a race car by any means but i would like to enjoy driving it. thanks for the comments thus far, just looking to see what someone got power wise, not just peak numbers but the whole curve as well and there opinion on how the cam performs.

You are describing the tsp stg2 and 3 high lift truck cams to a T. Not all about peak and both sound good with GREAT drivability.

ill have to go take a look at tsp truck cams, i had only looked at the cam motion and btr cams before i stumbled along this guy.

G Atsma

If you go BTR, have it ground by Cam Motion. Comp is dropping the ball too much lately...

fbodyfreakls1

thats why i was looking at cam motion in the first place. i know they offer the best cam cores around. cam for my camaro is going to be spec'd by tick and ground by cam motion.

Comp cammotion and tsp all offer the same cores. The difference in cammotion is they use their 8620 core standard. That is why they are a little more money.
The main issue with comp seems to be surface finish from all the threads and videos.

fbodyfreakls1

according to their web site they use the 5150 core as a base then offer a 8660 as a mid line and then the 8620 as the top dog core. only a $50 difference between the 5150 and 8620 cores tho, makes that a no brainier. i also came across a elgin 216/220 114lsa cam as well for cheap. still looking around tho, thinking about bucking up and considering a blower grind cam for a centrifugal charger as thats in the plans as well. once i rebuild the 250,000+ mile 4l80

G Atsma

Yeah, just stay focused on what you REALLY want your car to do for you. If you REALLY think a blower is in your future, cam for it now. It will still run fine for now. Just keep it real, and have fun doing it!

I just wanna haul the kids, a camper and my camaro to the track. Catching a diesel truck or mustang off guard evey now and then would be fun too.

CAMMOTION PERF

For the record, the great majority of our 8620 cam cores are made in house by Cam Motion.

I did know that and meant to go back and clarify. When i said they offer the same cores i did not mean they get them all from the same place. My apologies for that part. I meant they all have close to the same options so to speak.

The 8620 is their standard ls core per their site though.
It shows their higher standard of quality as well for offering it as their normal core for ls grinds.

The problem with that is most of the people that ask about the cheap cams are asking only because they are cheap. They wont justify spending more money for any reason and no matter what you say theyll buy it anyway. It may sound harsh but its the truth. Its all over social media every day. Same reason for buying "low lift" or "drop in" cams vs a higher lift. I do understand staying on a budget but ttying to get better quality but you are selling yourself short vs saving for another week. You can stay with an affordable beehive like 1218/1219 and run a little higher lift on either intake or exhaust and not have a single issue at all over hundreds of thousands of miles and have a better spring than stock or ls6.

I do Have a email into cam motion about what they recommend for me, waiting to hear back from them. I also did notice last night that in their section about there cores they do say the 8620 is standard core. I just assumed it was the other way based on the cams i looked at give you all three options but defaulting to the cheapest core, my apologizes there, i wasn't trying to argue so i'm sorry if it came off that way. as for being cheap that is correct. haha I grew up poor and straight out of high school landed a job in a body shop doing restorations making what was good money for a 18yr old kid. I blew every penny of it and after i left there had some hard times for a few years. Now im 27 with a wife and family, a good job as the diesel tech at a gm dealership and have a SMALL "business" working on go fast stuff when i can here and there. I don't like spending money, unless its on my z28. I know better than to be cheap but i just cant help my self at times. As much as i love my suburban i have a hard time wanting to put a $450 cam in it. Especially when i want to get it on the road asap and tuned so i can start saving for the blower. Just a insight to my mind for eveyone

The 5120 isnt the cheapest core by any means either. There are other lesser cores. It is great quality that is good on the budget also.
The lobes themselves are what makes the power. Ive tried so many on my personal stuff and customers its hard to count. I like the TSP high lift truck cam for their potential and quiet operation. Nearly every company wil give you the same duration range for your intended use and maybe same lsa, but digging deeper is the key to getting what you want. And i dont just mean numbers

I wish hot rod or somebody would do a truck cam shoot out. that would make mine and a lot of other guys lives easier!
