The dealer is full of crap. Don't trust the garbage they tell you. The repair should only take you 1 hour. https://www.gmpartsdirect.co/oem-parts/gm-converter-and-pipe-22948166/?c=Zz1leGhhdXN0LXN5c3RlbSZzPWV4aGF1c3QtY29tcG9uZW50cyZpPUdDMTUyNjU1JnI9MSZhPWdtYyZvPXNpZXJyYS0xNTAwJnk9MjAxNCZ0PWRlbmFsaSZlPTYtMmwtdjgtZ2Fz Click the link and it's your Y-Pipe. Loosen and remove the flange bolts, loosen the flex pipe clamp and remove the assembly and replace with new one. It's SUPER easy.

Yeah, I've seen these too. They are pretty nice and work well. Goat Garage did a nice work up on them.

I didn’t say Gwatney ports the TB. I just stated I had one too. It does wonders for my set up. I thought about the high ram from Holley. It just does t make sense for me. I don’t race my truck. Just an enthusiast with a hankering for power.

I don’t need it. My L86 intake is ported. I also have a potted 95mm Tb. I’m forced induction too. I was just saying to the guy asking the questions that their ARE intakes that fit the bolt patterns. also, Gwatney does the porting service. Www.gwatneyperformance.com

If you're keeping your truck N/A go for it. If you're going turbo don't bother and if you're getting SC you'll want a bigger TB. Other than that I wouldn't bother. If you want a N/A Intake and TB combo get the Atomic with 102 Nick Williams or 103 Lingenfelter.

You’re not going to notice. Are you going to have it tuned?

Hey guys, So finally got my truck back. Not going to get into the specifics of what's been going on. There are TWO videos on my truck at the following link. I'm focusing on the final dyno video (for now final Dyno, more to come ). Feel free to watch the other {8 minute long one} Ted gives really good advice. FYI** The transmission is not supper happy with the amount of HP/TQ going through it. I will be going back to these guys for a rebuild that can handle the upcoming power goals. Also, in a year or so I will need to rip everything out of the truck since the design isn't optimal, practical or built to last. It was built for a paycheck. That being said.....THIS THING IS AWESOME!!!! .................now. If the link doesn't work here is the url. facebook.com/jannettyracing/videos/491169901779184/ At the end of the day we ended up at 747 whp and 721 tq. When I bring it back we're going to shoot for 1000+. PM if you want more info.

For premature oil consumption and Blow By. Typically this is caused from the engine not being broken in properly. You need to get the engine up to 2500-3000 RPMs for a couple miles and let the engine slow down under vacuum. Doing this several times properly seats the rings and landings. After 50-100 miles of above procedure you're all set to tow, haul or pass under WOT etc. What prevents critical failure are the materials the pistons, rods and bearings are comprised of as well as the build procedure. Keep in mind One GM factory worker can build anywhere from 3-5 engines a day. During the build process each component including the block is absolutely drenched in lubrication. This help for when they go through leak testing, compression testing, fine lubrication and then they're dropped into a vehicle. For older vehicles it's just normal wear and tear. Extended warranties are your friend. As you've discovered :).

You would need the engine wiring harness that fits the engine model as well as the ECM. They will need to be tuned. If the engine comes with the harness and ECM you're fine.
