how are they better exacty?

danhr

better oiling and more stability (they are good to up to 8500 rpm's I believe).

sam pace

The LS7 lifters and Cadillac race lifters both have the improved oiling setup.
The race lifters have ceramic internals for higher rpm stability above 7500rpm's.
BTW:
The race lifter is actually rated for higher rpms. The racing sanction that these motors were in LIMITED them to 8500.

simple

could anyone elaborate a little on this?
SDPC doesnt list this part# on thier website, or atleast i couldnt find it.

is there a new part number for these lifters?

EDIT: found them on GMPartsDirect for $99.74

BTW if you are buying these, out of box but not used, you should expect to pay around $200-$225
New it looks like $300ish

I just found a set that are new that a member is selling, glad Im glad I am getting them

hi, you must be the used parts moderator. i am just wondering exactly what formula you used to calculate the depreciation of these parts in order to properly set a value for them.

personally if there new and not used i would expect to pay a bit more than 200

Hi, and you must be the Elitest ***** who's gonna bash me for offering info... That's ok here's the answer to your question...

I don't want to lose you on this so follow closely:
I searched, I read... I came to the conclusion that these parts are approximately found at this price. I'm ceratin there are places to get them cheaper, or more expensive if you fancy the high price stuff.

What it comes down to is that my name isn't Alan Greenspan and I'm not setting the prices or interest rates on anything. Just thought I'd offer some info up.

if i were bashing you i would make fun of your "rolled" bearing or your twin turbo "headers" lulz. just in case thats over your head it would be a spun bearing and turbo manifolds

it was a joke relax

personally i think the ls seven lifters will be just as good as the caddys and much cheaper. but again i would expect to pay just a bit more than 200 for a new set that was only opened and not used

but then again i am not building a 4 digit motor so i am sure you have done more research than me

I have the Caddy LS7's in my LE2 setup they seem like a great piece car sees 6500-6600 RPM no problem. Defiantly will need a shorter pushrod, the cups are a lot shallower than the OEM lifters just something to keep in mind.

How much shorter than stock did YOU end up with. After my rebuild I ended up using stock length push rods, but now I have several broken clips from my comp r's after spinning past 7,000 rpm, I may try either the caddy race lifter or the ls7 lifter.

With the right springs, the hydra-rev kit will do nothing. I literally gave one away and it's been sitting of a shelf for four years.
