Melling Stage 5 Gen 3-4 LS Hydraulic Roller Camshaft - Camshaft Shootout Cam
This Melling Hydraulic Roller Camshaft is the camshaft from The Weingartner LS Camshaft Shootout. Out of 23 Entries this camshaft placed 13th ahead of a Custom Camshaft entered by David Vizard and several other popular shelf and custom ground camshafts.
This camshaft has 2 dyno pulls on it, it has about 20 minutes of run time on it, basically brand new!
This Camshaft Produced the following Results:
647.7 HP @6700 RPM
553.7 lb/ft @5200 RPM
543.4 Average HP from 4000-7000 RPM
517.3 Average lb/ft from 4000-7000 RPM
This camshaft has a 1500 RPM Peak to Peak Power Band making it even more impressive.
This is our Intro into the Cam Challenge on youtube HERE
We entered 2 Camshafts in this Competition and WE DID NOT USE SOFTWARE
We ran all the data for the test and used a calculator and then chose 2 camshafts that anyone could purchase.
This Melling 22502 Camshaft had the 2nd least amount of Overlap from all the entries that finished 1st-13th. The only other camshaft that had less overlap was our other entry that finished in 5th place. This camshaft will idle below 1000RPM, make vacuum for power brakes while still having a healthy chop out the exhaust. This camshaft profile really is a sleeper among the 100's of LS camshafts on the market, and we have the DATA TO PROVE IT.
This camshaft has .625" Lift at the valve with a 1.7 ratio rocker arm meaning that it will work with factory rocker arms and not destroy valvetrain parts!
This camshaft will require a valve spring with the following specs:
150-175 on the seat
417-448 open
409-420 spring rate
The majority of LS valve springs from Melling (466594), BTR Racing, Straub Technologies, PAC, or PSI will work. They are usually rated for .650-.660" Lift and if you shim them properly the entire valvetrain will remain very stable.
