Anyone in here ever put an LS9 camshaft in a 5.3? Wanting to know if I need different pushrods. I know I'll need different springs and I've got new lifters. Also will I need to relocate my cam sensor?

In regards to the pushrods, stock "should" work but its best to measure just to be safe.
You will need an ls2 front cover that mounts the cam sensor on the cover. Also, you will need a 2005 ls2 1x cam sprocket, cam extension harness, a new chain and an ls2 chain dampener(trick flow sells a dampener kit to work with the ls1 block).
If need be, I will be glad to help out with part numbers, just let me know.
I recently finished my 5.3 short block and used the trick flow dampener....well made product!!!

If your chain is still tight it won't matter, just swap it onto the new gears. To me, it's cheap insurance to install a new chain if it's already apart.
The dampener isn't mandatory, just another peace of mind parts. It prevents chain whip under instant deceleration which could cause the chain to sling itself from the sprockets!
If you work at a dealership and can get chevy parts at discount, the $$$ saved on discounts would ease the blow of the $50 trick flow kit.
Sweet. I think the LS9 cam is going to happen then. I called our chevy store and they looked up part numbers for me and they use the same pushrod for every LS lol. 97 vette to 2013 corvette zr1. Looks like I'll have about 300 in the swap then.
Yeah, from my understanding the pushrod length didn't change which allowed GM to interchange and use leftovers on each new LS platform. I'm pretty sure the lifters stayed the same as well in regards to dimensions....but they improved them as the LS7 are supposed to be cat's meow lol! However, the Gen4 changed that trend when GM introduced the AFM/DOD nonsense!
Yes I agree. I was looking at going with megasquirt but I already have a stock harness and computer so I think I'll go that route and order hpt. We will see. ldr will be a big help I'm sure.
You would be better off with a used LS2/LS6 cam... if you do stick with the LS9 cam be prepared to set your shift points rather high. Beehive springs will work, but don't assume that the LS9 springs are sufficient because those engines had lighter valvetrain components.
