You did a nice job softening the C chambers and removing the heat sink for the spark plugs. Couldn’t tell if you widened the openings any, I like to open cathedral heads .100” or 1/10 of an inch using FelPro paper gasket as a template and then blend it inward, remove bolt Boss and eliminate swirl ramp completely .

You have simple logic in mind for theory of flow. 👍

Bad ass man. Keep up the great work. But what exhaust are you running. From header to the end of exhaust. Sounds amazing

Can you change the speed when the overdrive comes in

Damn that thing is healthy

not bad

Im sure its been figured out by now but 94% hurts it, a little bigger valve might help bring the angles back in, which it needs to help turn the air. You dont put a bigger door in without changing the door jamb, bigger door bigger door jamb. In this case they put a bigger jamb in but they left the little door on it. You have to work the percentages, the throat and bowl has to be proportionate to the valve. A little shrouding from an oversized valve wont hurt as much as that 94% throat.

Awesome

Owwww. shit his speedometer needle nearly broke off hehehe cuz you know that old truck wasn't made for that much squirt down the pouch 😭

this is so bad ass. Gotta love the M roaster too, makes the swap that much cooler.

Bro revered it out way to much last run 🤣🤣🤣 mf was laying over bad

💯💯💯

Nothing helps more than a proper valve job youd be surprised at the gains.

Sounds good brother. I've got a 2016 sierra 5.3 2wd. It's stock besides a 93 PHP custom tune. I believe I'm going to buy these header with Y pipe and leave stock exhaust on. In my videos it's the 0-60 truck

That's awesome man. I had a 93 Mustang GT years ago with the stock AOD transmission, Flowmasters, 4.10 gears and 13 degrees of initial timing. It only ran 9.40's in the 8th on street tires. That's impressive for a quad cab truck

Any updates on this build !??

Did my 1st #operationls & now awaiting oil and oil pan gasket from Amazon I lightly gasket matched and smoothed the inner surfaces better than stock Chompada? Cam from Texas Speed with springs and pushrods, Michigan Motorworks? Rocker arms and put washers in oil pump, and centered oil pump using all the tricks I learned off youTube

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣Heart Attack

Once you got a tune how much power and did the flat tops make good torque

Something’s gotta be wrong, my fathers bone stock 5.3 crew cab 2wd with 2.23 gears and stock 4l60 ran 16.7, after truck Norris cam only on just a 93 tune it ran a 14.8, I’ll gladly send you proof and tell you who does our tuning if you’d like

I got a cammed 5.3 just straight piped it and it’s quick plus I got a 1200 stall perfect for my cam next up a intake and a tune

It blows my mind I drive a 99 Dakota rt and it pulls a bit better numbers than Newer trucks lol

What heads are you running?

What did you use for your cold air set up?

Working on this same swap myself, what parts did you use for the intake? Very nice placement

Ouch. My bone stock 2003 4x4 2500hd crew cab with a 6.0 ran a 16.4 bone stock.

11:00 Is that a big hole in the intake runner I'm looking at?

What gears did it have before ?

What did you use for your cold air intake setup? Outside the cardboard Lol

Long tubes 7/8?

Alot of people drill/bore out the iac tunnel on the cheap Chinese TB. I don't think the Chinese throttle body is bad. It just needs to be worked in order for it to be good. If you're willing to put the time and effort into it it's not a bad TB

How did you eliminate the pcv on the chineese tb

How it run after the new throttle body? No tunning after that?

How do figure how big you want your cross-section area?

Thanks for sharing the video. It's useful to see if a cheaper throttle body is worth buying.

I got two question which you might have said in the video but i couldn't hear, Are you able to hook up the 1 3/4 long tube headers and Offroad Y-pipe up to the stock exhaust and do i need to get a tune immediately?

China a sabotage of Americans

Brother you sound like Randy Travis. Maybe just on camera I don't know. But you Def do lol.

What gears would you recommend for a 2003 5.3 built from the block up it’s a daily driver but I’m wanting more top end but also wanting to keep acceleration and towing capacity

I live in CA. Have you had any problems with Emission or getting the Truck Smogged if thats needed in your area

Now it just needs gears and it will fly

Have to say that motor is veryy clean

Just wondering how you determined you had an intake restriction and that it was the throttle body and not air cleaner or something........

He was faster before the gear swap I don't understand

Witch voodoo roller is this

What was your time in the 1/4 mile?

I'm surprised the BMW wasn't quicker? My BMW is high 12's and 4.4 sec 0-60 with a custom tuned 4 banger.

Hi i did the same build an ly6 6.0 in a z3, i went to the drag Twice and broke my axle twice in 2nd gear..What axle are you running i have 550hp and 255 rear tires.. Thank’s!

I know this is old but looks like u need push rod guide plates to stabilize rockers and push rods might have caused the failure

Love it! ive always been A GM guy
