Default Ls7 lifters and lifter trays

Is it necessary to replace the lifter trays when you upgrade to ls7 lifters in a ls1? Why would you replace the lifter trays?

No it's not required. If yours are old I would replace them.
New ones are not that expensive.

Naw just depends on how many miles you have. They're like $20 to change the trays, you don't HAVE to but why not since its such a cheap upgrade? If your car has more then 40k miles or is older then a 02 I would just change them for the hell of it since it's such a cheap thing anyways.

LS2 trays are supposed to be a little better than stock, or so I've read. I think it has to do with the trays not allowing rotation of the lifters within the trays at high rpms. Of course, just what I've researched...I bought the LS2 trays for my Torquer 2 swap coming up soon.

A set of 5 (they come in a box of 5) LS2 trays cost $12 new from a sponsor on my last build. A new tray should have more friction to reduce the chance of lifters falling out during a future cam swap, and also should be snugger around the end of the lifter to reduce the chance of it spinning. I say $12 is cheap peace of mind. If you have the problem in the future at least you know it wasn't because you didn't spend ~$20 while you were in there.

My bad, it wasn't a sponsor, it was a dealer in the midwest. I got them for $3.02/ea but had to buy a box of 5 because they wouldn't split up a box. This was mid-2008 though. Now it appears the cheapest you can find them advertised are $5-$6 each.
