Might wanna gap those rings. Givin em a lil breathing room will keep your pistons in 1 piece.
You literally mentioned nothing about boost prep.
Good clean prep work! 👊
Did you gap the rings or nah?
Literally the most important detail all the shit he did is not half as important
@@FirstLast-tx3yj unless that motor had a lot of miles on but still better safe then sorry to gap them rings.
Sloth- they be better off if the engine had a million miles if they are not tapping those rings
I hear you don’t really need to gap them if you stay below 700 ish hp. If he’s going over that then yeah the motors at risk
Gap those rings!!!!!
My p71/Chrysler killer build for my super sport s1 gmc
I just subscribed. Where are you located?
We are based out of New Mexico
Hello I’m build turbo ls
5.3I have stock Internsl
Should I use the same rods and pistons or what combination can I used so it can hold more boost
What did you end doing bro? I'm sort of in the same situation I kinda want to just leave it alone throw a cam in springs and lifters and just fucking send it.
@@rodm2345 Cam lifters and stock internals is perfect combination seen that combo on multiple Tahoe's go 100k miles. the pistons in lm7 5.3s are pretty good at handling anything NA power. Definitely get a after market air intake if you do the cam, it makes a huge difference.
@Thefoodcan Thanks! Now a question I've been asking alot is if I'm gonna run turbo do I have to gap rings? I've been reading that you do but then I see that you don't have to if you're only gonna 5-15 pounds of boost. I'm confused
@@rodm2345 When you add boost at any level psi you are adding extra heat to the pistons no matter what, so I would gap them no matter the amount of psi you run.
@@rodm2345 Air intake manifold and intake, long tube headers, a mild cam and then upgraded valve train with arp head studs and most important my heads are ported, this is what I run. I am at 510hp on 93. Since you have to upgrade the valve train go with the best you can get as in my case this also opened up the opportunity to run nitrous if I wanna race someone and gap them.
lol he didn't boost prep at all
You plan on selling the alumasters on the Vette, brotha? Lol.
they actually already sold haha. sorry man
Well, that was a terrible effort
How to boost prep a LS motor: get one with over 140k miles, run E85, that’s it.
Why over 140? Lol
@@probablyonahonda more ring wear/gap… means lower compression= cooler operating temps for boost applications that run hot
@@jordanwilson9440 ah yes thank you
Jordan-exactly
Are u sure that's a 5.3,it doesn't have dish pistons a 4.8 has flat tops.
Ya its at l33 they have flat top piston3
That's an L33. The L33 is an aluminum block 5.3L that came with the 799 heads and flat top pistons from the factory, which gave it a stock compression ratio of 10:1. They are kind of rare since they were an option in only a few 4x4 trucks for 3 years IIRC. they are also known as the "5.3 H.O." or the "baby ls1". The L33 weighs right around the same as the iron block and iron head 4.3L V6.
what car would you find one of these engines in? or is this a custom built engine?
this would be found in any GMC/Chevy Truck,Van,Car etc. 4.8, 5.3, 6.0 can all be found in these cars.
@@GOTboostFILMS is this a gen 4 or 5 engine?
@@MrAmerica69420 looks to be a gen 4 by the hole in the timing cover
@@MrAmerica69420 its a 4 it doesn't have a vvt cam
It looks like an aluminum block 5.3L L33 engine. That would explain the flat top pistons and the 799 heads that should have came on it from the factory. The L33 made 10:1 compression from the factory BTW.
