Works great

Great pump for the LS platform

Great fit

Perfect works great!!

This is a high pressure oil pump because the relief spring is longer and stronger. Issue is the plug to it was impossible to take off even with a torch and impact gun that plug in it wouldn't budge. I ended up having to toss it because the plugs head stripped and wasn't ever going to come out. Just buy a high pressure spring and save yourself the trouble and money.

Unfortunately got package delivered extremely banged up, looks like 58 year old Mike Tyson went 1 round with this thing before it got delivered to me, sadly I’m on a big time crunch to get my build up and going and I’m praying that it works as it should. Even my stickers came messed up 😂 -5 Horse power for me i guess….

Before I installed this pump my truck would idle 30lb and build to 40lb no issues with stock pump. I installed new lifters and this oil pump now my truck is idling 10lb but does build to 30lb driving when hot. Overall don’t recommend, I primed oil pump correctly and even before first fire pulled fuel pump relay then cranked engine over to build oil pressure just to double make sure I would be good. 10/10 junk and will be replacing with a stock pump.
