CAMMOTION PERF

There is no lower RPM performance penalty when using our LLR solid roller cams. They will perform equal to or better than a hydraulic at any point in the RPM range in an equivalent grind.

I need to read through your thread. I remember glancing at it, but haven't had a chance to read all the way through it.

I'm anxiously awaiting cooler weather so I can get back to the track now that the tune is finally fixed.

This heat has completely demotivated me to even bother getting the car out. Black car, black interior, no a/c, and high 90*s with high humidity = me taking my *** to the lake and soaking in the water in all my free time

I hear you on the heat. This past week in Missouri has been hot as hell too. I had to take my car to get inspected yesterday, and in order for it to pass, I had to drive over 2 hours round trip. Needless to say I was glad I still have AC.

I will be looking into adding it back to mine. I'm old enough now it's a bit more appealing to me than an extra .1 in the 1/4 lol

I think I still have the compressor for my Corvette accessories and most of my Chevelle factory a/c parts. It was working great then started freezing the lines at the expansion valve so I just pulled it all out. Dumb decision.

Pretty awesome results!

Does it peak at 6500rpm due to the MSD intake hitting its flow potential.... or would a bigger cam peak higher? 93 octane is impressive to yield these numbers!

So exactly what is involved in switching over to this cam? Lifters, cam as well as adjustable rockers and changing valve covers?

cam
solid lifters
pushrods for correct length, most use a thicker sidewall pushrod too
adjustable rockers
tall valve covers

or if you wish you can use arbor shims under the stock rocker arms to set preload in combination with pushrod length which is how I did mine...cuts out the cost of rockers/ valve covers

Springs if you aren't running something around 150/400. Likely at this level you already have qualifying springs.

NAVYBLUE210

Talk with Kip or Speed you will pick up .3 @ 3+ MPH minimum
with the Equivalent Cam roughly + 5*-7* bigger to account for lash,
Same driving manners ~500RPM + Peak HP and another 500RPM
Carry before nosing over!

Springs 170/430 Minimum, I'm running 190/470.

While our customers cars have consistently picked up power, there is no specific amount that we can say you will gain with the LLR street solid cams. Some of the results you see were also a result of cam spec changes.as well. So results will vary. Spring pressures will depend on application, but our standard LLR solid lifter lobes are designed to be just as street friendly as our hydraulic lobes. In many cases, customers retain the same springs that they would use with a similar hydraulic cam.

Correct, I kept the same set of BTR springs (had a machine shop test them for wear).

While mine has gained in the 30rwhp range, I increased duration and overlap 4* over the size of the hydraulic (not accounting for the additional duration needed to make up lap)

To clarify I was running a 230/238 with 8* overlap. The solid roller grind is equivalent to a 234/242 with 12* overlap (actual specs in my signature).

The rest of your statement is true. The car drives the same and runs the same down low. Around 4,800 rpm it's like a light switch though and from there it rips as far as I spin it.

I only chose to alter the specs after speaking with Kip because I was running the same basic cam in my LS2 as I had in the LS1 and it brought the power band down more than I cared for. With the hydraulic the car was nosing over a little early...around 6,000-6,100 and then falling off pretty quickly so I had to drop shift points to 6,400rpm get my best ET.

The new cam pulls to 6,400 before peaking then tapers off much more slowly. I'm thinking about taking shift points all the way to 7,200 and see how it does. Best pass so far has been shifting at 6,800 but I was having tuning issues and didn't want to push the limit until they were resolved.

If definitely gave me more usable power on the track and also for holding gears during spirited drives on curvy roads. Another huge plus for me is I no longer have the lifter clatter after making 1/4 passes like I did with the ls7 lifters.

What lifters are you running thunderstruck507?

thunderstruck507

iTrader: (18)

Morel drop in solids. They are the standard lifter Cam Motion pairs with their LLSR from what I gather. Mine even came in a Cam Motion box rather than a Morel box.

Prior to the swap I had LS7s also from Cam Motion. On previous hyrdaulics I have ran Cadillac Racing lifters and even a set I pulled from a rebuilt Vortec 350 truck engine. The Vortec lifters worked the best for me surprisingly. IIRC they have a longer travel range so I was able to set preload high and they never bled off or made noise.

Morel 5425 is what I use with CamMotion LLSR. Kip also suggested T&D shaft mounts for optimum valve train stability,FYI.

Morel 5452 (lightweight solid roller / linkbar) was what I was going to run, but I haven't had the chance to research anything about longevity yet and how that "lightweight" affects things. The T&D's are a given after talking to Kip about it. They are a NICE piece!
