Just like used car salesmen. They promise you the world, but once the deal is done, you get squat!

Let’s hope valve train and cam is top notch.

Not to hijack, but to add to this build so if you decided I'll leave it at that..

Not to scare you or anything but a lot of guys were complaining about failed ls7 lifters a few years ago. I avoided doing lifters with my cam swap and I regret it now since I had the stupid things in my hands and didn't want to risk it. A lot of them were Vette guys and I think there were some defective heads that led to their problems and some cams with bad lobes and race specd cams so overall I don't think it was the lifters.

I'm curious which ls7 lifters you get since BTR sells them but I don't know which ones are the genuine GM ones. @67427ss is running them and his engine sounds great. I'm thinking about ripping my heads off and doing mine.. only issue is they have like 3 different ones listed ranging from $99-over $200..for Morels..

Here is the kit I got, I believe Matt has the same one. I don't know enough about lifter failures so can't help you with that, will tackle when it comes. It’s best to give BTR a call they will make recommendations. Thank you for head up.

sorry wrong box, have them at the mechanic shop already. So you don't recommend changing them?

Correction, didn't even get them yet. Ordered them last week along with the trays, too much going on at once lol
