how important is it to use LS7 lifters and chrome moly pushrods in the turbo 5.3 I’m building?

Well something has to open the valves right.

You could use Gen II lifters and stock pushrods.

Or more info.

What are you proposing otherwise? The LS7 is now the stock default replacement lifter, and chromoly pretty much the desired pushrod material.

Stock push rods are more prone to deflect as spring pressure goes up with more aggressive lobes on many aftermarket cams. Likewise rpm and valve train weight in a running engine can add to the deflection. One of the key parts of making power is to properly control the valve train in many cases the stock pushrod is less than ideal. Likewise many times when the cam is changed to an aftermarket cam or heads used that have been decked for flatness or increased compression a different length push rod is needed for correct preload. P-rods are pretty inexpensive so replacement & upgrade is a natural part of engine upgrades and hot rodding. Typically ~$135 or so

LS7 lifters are generally a good value oriented new replacement lifter for a lot of projects. If the heads are off might as well replace an old set of lifters while your in there when a?new cam goes in the engine. Used to be about $100 for 16 before the back order shortage. Not sure what price and availability is now.

I prefer to be more specific. If your 5.3 is say somehow a 2006 with 40,000 miles and you plan to run it stock with just a turbo, then you have LS7 lifters that are most likely in good condition.
If that was the case maybe pushrods and springs.

In other words if you want an answer with some sort of correct, useful, and worthy information you should give more details. IMO an answer should be as vague as the question. Why should anyone waste their time providing information that may not apply to what little information was given.

If you want to ask with less effort next time try this: "what lifters n pushrods should I use 4 my LS turbo build" Less typing, same point. No one has needed information to provide anything other than a generic answer.

• ok so I understand that LS7 lifters and chromo pushrods are pretty critical. 99 Black Bird, I only ask because if you watch YouTube some people do and some don’t. I’ll be building this for a customer. I’m trying to build an estimate. I’m not in the habit of billing my customers for parts they don’t need! I figured what better place to go. No need to be a DICK! And belittle people who are less experienced than you. While I may not be an expert in LSs yet, I am quite knowledgeable on sbc and all manner of older GM. It’s an 02 LM7, so I defiantly need to upgrade.

Guess you're referring to me being a dick?
Thats awesome that you have a customers car and you're building it off youtube videos and forum answers.

Before anyone else calls me a dick first answer this: Do you want to pay for your car to be worked on by someone who is building your car like this? Sure I can turbo your car for money. (I'll learn by doing from youtube) WTF?! REALLY?

skymangs

He is only paying for parts, no labor. And he knows he’s a Guiana pig. I’ve built many LSs, just never turboed one before. Both I and my customer know I’m good at what I do. And he won’t be disappointed. And yes, you are a dick!

yup, you try to ask legit question.

G Atsma

I read this whole thread so far, and nowhere is Blackbird being a dick. He gave you some very solid and safe advice for putting good fresh parts in an engine.
You say you are good at what you do, and that the customer will not be disappointed. Yet you come here for advice and call the person giving it to you a dick.
Truly a legend in your own mind....

skymangs

That has no similarity to what he originally posted. That response is genuinely helpful. The post in question (before he edited it) basically called me a lazy piece of ****!

skymangs

And yes, he’s still a Dick! You can’t just edit and delete your way out of Dickdom!

He edited his stuff because he was recently given a warning about this type of stuff. He’s trying to cover his tracks now...

skymangs

I was going to say... That was NOT the post that I responded to. It now looks like I called him a dick out of the blue! in his original post IIRC, he offered no advice and just ranted about me being lazy and pretty much insinuated that I was stupid. Very condescending. I still feel my response was justified!

G Atsma

Wow, I had no idea about the "other" post! I take back my comments about you,and hope you can accept my apology!

skymangs

Sure can! I am a member of many boards. And I’ve never been accused of any wrongdoing. I joined this board because more and more my customers want LS swaps. I’m the kind of person that I want to be on top of all the latest developments. I offered my customer (who happens to be a friend) the opportunity to have a turbo installed for just the cost of parts if he would allow me to experiment on his truck. (I specialize in 47-54 Chevy Trucks on an S10 frame) I make the same offer to various friends whenever I want to try something new. I’ve been researching for weeks and I feel I have a thorough understanding of turbos now. I never attempt anything for a customer unless I’m confident of success! I am not a legend in my own mind.

G Atsma

Well stick around skymangs! Plenty to be learned around here. I know I have!
Cool you mentioned the 47-54 Chevy truck/S10 conversions. Makes for one cool truck with better suspension and chassis parts.
Nevermind the "legend" remark. That context died.

skymangs

Here’s my S10 swap how to thread on the 47-present GM truck forum http://67-72chevytrucks.com/vboard/s...d.php?t=632686
yeah they do make a pretty cool truck!
