LS3 Lifters Options and Opinions - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

LSX Camaro · 02-13-2013, 10:44 PM

Looking to get get some feedback on 2 different LS3 lifters by GM. I am in the process of a LS3 conversion on my 2010 L99. I had a custom cam designed and am deciding between different lifter options.

1. GM #12499225
LS Series camshaft lifter kit
An inclusive set of 16 lifters for the LS Series engines.
Newly redesigned for high RPM LS7 engine usage.

2. GM #88958689
DESCRIPTION: LFTR PKG set of 16tested to 8000 RPM
same dimensions as production
improved dynamics and stability at high RPM's

The price for the second part number is almost double. Any thoughts?

1sikRS · 02-13-2013, 10:53 PM

I used comps 8610s I Believe but I don't Spin my motor anywhere close to 7 or 8k rpms

trw427ss · 02-13-2013, 11:08 PM

Not sure of the part # but the GM Caddy Race lifters are better than the LS7's.

tandtperformance · 02-13-2013, 11:11 PM

second one listed is the set to go with .........

K32 Camaro · 02-14-2013, 02:55 AM

Always the one with the bigger part number. That means it was made at a later date with better tech. (I was BSing.)

Go with the shop guys advice.

First off what cam are you going with?
What lobes?
What will your spring pressures be?
What are you planning to be spinning to?

Your doing a very good quality build bud so start researching.

If you'll be using your stock lifter trays and want an awesome lifter thats BETTER than the stock GM's, look at these lifters by Brian Tooley racing (he used to own TEA) an awesome guy and an even better valvetrain expert. Give him a call
Here are his SLR (slow leak down rate) lifters.

Now if your gonna be spinning it hard and pretty high and you want to not worry about spinning one in the bore due to lifter tray failure due to high rpm and high spring pressures and lift then I'd go with these:
http://www.briantooleyracing.com/mor...r-lifters.html
I used these on my 4th gen

BUT PLEASE some people here think that because its 8k rpm that they are the best. They are NOT!! There are ALOT of failure rates with these lifters because they MUST be setup appropriately!! And even when that have been still trouble since they came out. Search on Ls1tech and you'll see.

Keep up the awesome build bud.

VADER SS L99 · 02-14-2013, 05:32 AM

Yeah there are alot of failures reported on the caddy lifters. I think those need a really light valvetrain and certain springs to work well

CGT · 02-14-2013, 08:52 AM

I had the Caddy lifters take out an entire ls2 when one of the axles walked out of the lifter. Trailblazer SS, mild cam, ls3 heads, decided i was gonna "upgrade" to those lifters. Maybe it was just bad luck, but I wont be using them again.

The cam is a custom grind from comp.
Lobes are EHI and LXL
Intake lift .638
Exhaust lift .612
Rev limiter will be set at 7000
Springs are Patriot Gold Duals

litle88 · 02-14-2013, 02:20 PM

What about duration?
How often will it see the track?

It doesn't seem radical, I think that the Brian Tooley lifters will be your best bet, you didn't cheap out on a single part of your build lol not even the plug wires. Don't do it on the lifters especially lol.

realcanuk · 02-14-2013, 02:52 PM

Usiing Morel link bar lifters from Brian Tooley. Give him a call. He will steer you the right way.

litle88 · 02-14-2013, 04:04 PM

Here too, too many people cant be wrong lol.

LSX Camaro · 02-19-2013, 05:32 PM

Thanks for the advice and opinions. I went with the BTR lifters and springs.

VADER SS L99 · 02-19-2013, 05:39 PM

What kind of reliability do those lifters have? I'm thinking about those or Morels for my next build. Pretty sure a destroyed lifter has ruined my motor so next time I need something better than LS7's.
