High Performance Lifters
Hi,
I've been doing my research for my ported heads/camshaft swap. I've selected hollow stem stainless steel intake valves, Inconnel exhaust valves, chromoly pushrods (waiting to check proper length during swap), stock rockers with comp cams trunion bearing upgrades, TSP camshaft, ported cylinder heads, ported oil pump, full new gasket set, double spring kit with .650 lift with titanium retainers. With all this said I am having a hard time deciding on performance lifter upgrades. I hear the LS7 from the ZO6 setup are a great choice. I'm really trying to create a high rev naturally aspirated setup. I've talked with shops and they haven't had much input on which is the better way to go with performance lifters (They usually say all the aftermarket lifters are great choices). I also have been looking at CTS-VR roller lifters that seem to be a good route to go. Does anyone have recommendations from experience? Thanks

My feeling has been the LS7 lifters are a great performance & economical choice. I'm sure I wouldn't be disappointed with them. I'm hoping to hear from some people who went with performance lifters other than the LS7 lifters to just get some "different" experiences. Thanks again for any input

Lifter choice
Running the GMPP high performance lifters in my LS7. At 7200 rpm nothing has fallen out yet.
Also a great price |

Your LS3 lifters are the same as the LS7 lifters. If they have a lot of miles on them you could put in a fresh set with the new cam.
But with the set up proposed, I still would only add a couple hundred to the rev limit from the stock LS3 6200. Maybe 64/65 ish. To get to that 7000 + rpm like an LS7 is capable of you have to look at the other things an LS7 does to accomplish that. Ti rods, Ti intake valves, good crank, light pistons... If you do build an all out high RPM LS motor, look at Morel lifters and bring some big $$$$. Not need though for a head/cam LS3, the stock LS3/LS7 lifters will be fine for a mild street cam. The GMPP performance lifters would be a step up from that if the cam/springs are aimed at real high rpm, and Morel tie bar lifters being the top of the line if the budget allows. |

I heard that the LS3 lifters are different than the LS7 lifters. Is this not true?

In the GMPP catalog, they only show two lifters - the OE replacement which it lists as an LS2, LS7 application. And then they have the GMPP high performance lifter for high lift/high rev application. When I bought some LS3 lifters from a dealer, it was the same pack of 16 part number shown in the GMPP catalog for the LS7 application. So I'm thinking they are all the same.
Another good idea is to check with the cam manufacturer. If they are an actual cam manufacturer they will have spintron tested valvetrain combinations with that cam and will know what lifters, springs... will work best with it. You don't want to mix and match stuff, stick with proven and tested combinations. That's the approach the LS7 takes to get to 7000 rpm - a total high rev package. |
