Just been told to research these as non of you guys are using these anymore.
WHY?

I run this lifter in my 441 and yet to have any issues. I have heard a handfull of people having issues with these things and if i had a chance to do it again i would not have used them. I wanted the best of everything at the time and they were supposed to be just that. Come to find out if you compare the LS7 lifter to the Caddy lifter there is a comparable physical difference favoring the stock LS7.

I was told here in NZ by my tuner to use these, my engine will not rev past 6000rpm, with the cam i'm using it should go to 6500rpm. My tuner has said it's the lifters 'my comp lifters' that is causing this....

If the tuner saying to switch for a weight issue?
The lifters are on the slow side of the valve train. If you have issues with the valve train I would look at other things first. Prime example, the Morel is much heavier then the LS7 and they have no issues with high RPM.

I'm not to sure what his reason is, the comp lifters i've always used & with my first cam revved to 7000rpm.
When this smaller cam is being tuned it goes to 6000rpm then the power just drops off, cam is meant to go to 6500rpm, His fix is to fit the Caddy lifters

Valve springs are P/Gold
Can't post up my old Dyno sheet but torque & hp reach 6000rpm then both drop off
HP is still climbing at 6000rpm, Torque peaks at 4800, slowly drops then rises a bit at 5400 then falls away till 6000 then just drops

Pull the Patriot springs and test them. They are known to lose their stiffness very quickly. I have seen several tests on these springs after low miles and the results were poor. If they did lose their stiffness, this would explain the sudden drop in power at high RPM.

Man have i had issues.
I purchased a Fast 102 intake & 95PTM T/B from TSP, when it was installed here the T/B didn't fit due to LS1 water pump & T/B not sealing to the intake, TSP replaced the T/B with a PTM 102 & i bought a LS2 water pump from TSP.
The pump arrived without the thermostat & housing, 'great', so buy them from TSP, now today, 2 weeks later through usps the thermostat & housing finally arrive, 10 days later than should be.
Guess what!!! the wrong f--kn parts..they are the same as what i have, LS1, they are meant to be for the new LS2 pump...boy am i pissed!
The workshops spewing at me as they want the car gone from their shop, it's been there since July 26th.
I've missed my last road race meeting where i was leading the series, 3 reasonably big car displays i would normally attend, another this weekend & no doubt a drag day coming up on the 21st Nov.

That was done on mine also, but it still didn't clear due to my heads being milled .030. & the T/B cable 1/2 wheel also fouled on the pump due to the temp senser being in the way.
I have used an LS2 water pump that doesn't have the vertical housing protrusion next to the intake pipe but does have the same front cone shaped pulley.
The workshop has found the right Thermostat & housing, thank christ, so now need TSP to exchange the LS1 unit they wrongly supplied for the right one so it can be given back to the guy that gave his to my car.
