THE ULTIMATE 5.3L CAM TEST VIDEO-HOW MUCH POWER WILL MY CAM MAKE? FOR ANY LS CAM-THE ANSWER IS HERE!

[@merylpelosi8485]

Man, are we spoiled nowadays or what? Your stock LM7 cam makes more than 350 hp. Think of what it took to get an honest 350 hp out of a 1967 327 Chevy. Great job showing what a cam change will/will not do. As always, a lot of work and a lot of information crammed into 11 minutes of content.

[@HioSSilver1999]

Old 327s made that same power with a oe flat tappet hydraulic cam. They did have 11:1 compression tho

[@Matthewzilla]

Rich tested a 327 in virtually stock configuration that made 356hp @ 6100rpm. Again, it’s at 11:1 compression instead of 9.5:1.

[@merylpelosi8485]

@@HioSSilver1999 That was advertised HP. With an iron manifold and a Q-jet, the L-79 struggled to make it. Look what it took to make an L-76 or an L-84 put out their respective numbers. L-79 still one of my favorites, though.

[@75novaguy73]

I watch your videos from time to time but now its a bit more impactful as I think I will finally be pulling the trigger on an LS swap for my hotrod. Plans are mostly stock but intake, cam and headers are likely the only big upgrades not counting any supporting upgrades like springs and such for the heads. And the largest reason for wanting to swap the intake is for the look, that big plastic thing isn't exactly appealing and to just be rid of anything unnecessary. Might even go with a carburetor intake and run a Holley sniper efi or similiar for that more traditional feel. Idk yet.

[@rajcam80]

I sold a .02 over 5.3L with a stage 3 cam from Summit. It went into a Mustang!

In for all of the - "But Richard, what about this? And what about that? comments. This is me thinking out loud... 1. That Crane 200 duration cam - I feel like a factory LQ4/LQ9 cam would make almost identical numbers. 2. I love that old Crane 224/232 cam - I have a version of it that I had Comp grind on XER lobes. I'll be testing that in my LQ4 swapped Silverado soon. 3. Thank you Richard for the plethora of camshafts compared in this video. Great data as always.

[@keith6872]

Install notched pistons and try more overlap (106, 107, 108) installed 4 degrees advanced and earlier intake valve closing. I know more overlap hurts drivability, but makes more power thruout.

[@larryw5429]

I think these videos should have vacuum readings! Very important for power brakes!

[@TurtlDrip]

Hydro boost fixes that problem

[@CrazedPerformanceRepair]

Whats crazy is I did a 4in stroke to mine and even with the slightly bigger of the cams listed. That stroke caused the engine to make more tq than hp. I think the extra stroke combined with the restricted almost stock 706 heads shifted the max airflow to occur at under 5252rpm.

[@justinturdeau2383]

What are the numbers?

[@CrazedPerformanceRepair]

@@justinturdeau2383 it was on chassis Dyno in a 04 Tahoe with heavy tires and 4l60 so numbers aren't comparable and low. But still, it was 345 lb ft@4500rpm and 314 hp @5100rpm. Best part is I wanted towing and that's what I got. It has 300lb ft at 1700rpm and starts increasing slowly at 2k RPM until it plateaus from 4k-4500. So awesome towing power considering it's all right away.

@@DoyleShadduck You clearly don't understand hp numbers. This was at the tire without correction not some false stat gm gives out. GM inflates there numbers. stock on the dyno behind 4l60 is around 285-310ftlb at 4000 with a set of headers.

Come to find out my younger brother burned up the motor in 2019 and the only thing he could find quickly was a 6.0 that was supposed to go in an 09 Sierra1500 HD, but was a factory reject because of wrong angles on the cylinders. The machine shop my brother got it from buys these rejects and bores and sleeves them. I've determined it's not flex fuel and has 862 heads. So I'm 99% sure my Sierra 1500 that I paid $5,000 for has a YL6 with less than 80,000 miles on it that had been sitting in a shop from 2010-2019. 😃 I wish the block casting numbers were in a more convenient location!

Power up to 3500 rpm was not very different from the smallest to the largest cam. This is probably the truck intake manifold dominating the midrange with its runner length. Were all the tests run with the same type of manifold?

[@msh6865]

I have to wonder if the average custom truck or hot rod owner could even notice some of the small incremental gains on these cams? Obviously, 100 HP is going to register on the seat-o-pants dyno. But, 10 or 20 horsepower is most likely not even detectable when out cruising on a Saturday night. So basically when replacing a stock cam, it seems you need to at least throw in a stage II to see any significant improvement.

you will feel 20 hp

Interesting that the TN and BTR stage 2 cam have the same lift and intake duration, but the tighter LSA equated to more peak hp and tq, and started making power ~1700rpm sooner. In fact, the TN cam made more hp and tq than the next 218/224 on a 110 cam. I wonder why more LS cams don't have tighter LSA's?

Hi Richard, I'm an Automotive Instructor for Job Corps and I teach tuning. I have an extreme amount of dyno training but for the IM240 program from Colorado/California. It seems to me that lobe ramp rate, location of opening / closing on the degree wheel and LSA have greatest effect on Vacuum at low rpms as I know you know. We are an emissions state and many people want to use their Vacuum boosters without going Hydroboost. In Washington State, we are allowed to modify but HP and Torque numbers can only help so far. I've been watching the videos looking for vacuum on your control panel screen during your dyno runs but trying to see them at idle is tough because the video is typically about above 2K rpms.

@richardholdener interested in the truck norris cam for my 04 tahoe z71 with the l59 engine. What torque converter you think will go good with that cam? Daily driver i like dogging it at stop signs sitting on 33x12.5 x22s

2500 or less

I am wondering if you have tested the Summit 8713R1 LS cam in a 5.3 with 243 heads?

no sir

Whats the part number for the last cam and can you run it on stock pistons and valves?

What would you recommend for a 99 5.3 cam. 33 inch tires I want to run a 3400 stall converter.

Any thoughts on the cam motion junkyard dog camshaft, 238/254 .621/.604 115 in a SBE LM7

[@richardholdener1727]

very big in a 5.3L-if it fits p-v, it should make good power

@@richardholdener1727 piston to valve clearance is my main concern. I'll just stick with the original plan & buy aftermarket pistons

Is there a big difference with these cams when using EFI vs. Carb'd?

[@richardholdener1727]

the power differences offered by the cams are the same with either efi or carb

Can you do a video for the l92 6.2 with the tsp honey badger, and truck cams.

Isn’t the sloppy stage 3 Elgin 1841p more duration than the “biggest” cam shown here?

not sure on the ss3 specs

What's the cam that gives the best power in low range ?

see the results in the video

Depends on your application.... roll racing and ringing out rpm... top end power is valuable..... I shift my bolt on stock cam ls3 at 6500 but it wants more
