is it ok to reuse stock lifters? or am i asking for trouble
for a cam only car

 

If you are changing the cam I would change the lifters too - depending on miles to some extent. I know some cam only don't, but you risk premature damage to your cam or worse if you don't.

 

if you are pulling the heads then change them. the new ones are ls7s and are a better design. how many miles are on your engine?

 

If it's a higher mile car, I'd definitely do it. That's when it's a good idea just to buy some heads since the stockers will have to come off anyways.

 

change lifters

 

How many miles on your car? If its low mileage I would never pull the heads to do a cam only swap. That's just stupid.....

 

i agree!

 

From what i understand there the exact same lifters...there just called ls7's now.

 

ya that's what gene said over at gmpartshouse - same lifter just packaged together.

 

yeah the lifters listed for the ls1s are ls7. the old ones are no longer made,

 

They are not the same. They are direct replacement, yes, but are a different design.

 

if you go to a gm place and order the ls1 lifters you will get the ls7s, they changed the part number!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Yes, thats correct, but if you look at them directly, they have a different desing. I have an 01 and the new ones were different. I swapped them out in 06.

 

thanks for the info guys

 

yeah, they look different. So, im sure its a different/better design.

 

if you are pulling the heads off you might as well change the lifters.

 

the car has 103k on it. wasn't planning on pulling the heads until next year when i tear it all down. but i would also like to make it threw the summer. the car will only see around 2000 street miles and hopefully go to the track 2 times a month.

 

Should be fine no more then it's going to be ran, i'd probably stay away from LSK lobes.

I'm installing a G5x2 (x-er) lobed cam, only 40k on my car though and no way in hell am I pulling the heads for a cam install. I plan on heads next winter anyways and i'll do it then. Of course I'm auto and shift points will only be at 6.4-6.5k; so I won't be revving the absolute **** out of it.
