any reason behind that? Just curious because lifters are still on the buy list for me

comp R are extremely finiky on lifter preload. sometimes it can be hard to find the right spot. for any decent cam, i would use the LS7 lifters. for the more aggressive lobes, i would look at intended purpose, then go from there.

I bought some lifters off Gaterman Products. They are the Eaton LS1/LS6 lifters that GM put in stock in the LS1 and LS6 engines. I am shifting at 6800 and red line at 7K rpm. I am very happy with the product. The LS7 lifter cup is higher by .050 so you do have to measure and get the right rod size you should always do this with any H/C package. Now the stock lifters work well. I got into a heated discussion about the LS7 and LS1 lifters. I was very well informed and I am using stock new LS1/LS6 lifters from Gaterman Products.

what would be considered an aggressive cam? that seems to be the big question.

at what size cam would you NOT use an LS7 lifter.

well it depends on the intended use. you will know them when you see them......most of them are called spring killers. imagine how the rest of the valvetrain is effected

would that not be the threshold to define?

it is hard. like i said before, you cannot just say yes it will or no it will not. it is such a gray area it is hard to just say one will or one wont. peoples ideas of what is ran on the street differs, and so does intended purpose. that is why it is so hard to get a straight answer....because there is not one.

maybe that thread will help a little. do not let the LS7 lifter problem get blown out of proportion, all lifters CAN fail. there is always a reason though that is normally not the fault of the manuf of the part.
