I just installed the headers, intake, and Custom 3 inch mandrel bent exhaust, and noticed a big difference with the butt dyno. It pulls hard thru the gears but wish it was a 6speed. Next mods to come custom tune, heads milled to raise compression to 10.5:1 port matching intake/exhaust, 6speed conversion, and a turbo setup.

 

 

Hopefully looking at 500RWHP when done with only 8PSI.

Why mill the heads and then add a turbo? Why don't you keep the compression down low and then raise boost more?

 

 

ditto. High compression is accomplished with higher initial intake pressure OR tighter squeeze.

I said it wrong. I should have said that i will be milling a second set of heads, and use them untill i get the turbo setup.

5.3L should easily put 500HP @ the RW with these mods.....I think the turbo will put more (hope you got an extra set of tires to smoke) :cheers:

Wow! Will a second set of heads be worth that much trouble? The 5.3L is already 9.9:1.

I am not against getting the most out of a stock engine in a truck. But wouldn't it make more sense to go to this extent in a F-body car or Mustang or any car that is designed for it instead of a nearly 6000lb brick?

 

Even if you get 500 RWHP, you will still lose to just about any V8 car with similar mods.

 

Just my .02

will either one of those be able to pull a load? hmmm, just a thought....though I have no idea if the truck would be used to pull anything with these mods.

Making a truck fast is more challenging. Anyone can make an Fbody or a Mustang fast. Plus with a truck you can drive thru deep snow, tow stuff, haul a couch in the bed, all kinds of stuff. It's an all in 1 package!!! Besides even if you do put similar mods in one of those cars, there's always someone out there with more mods, whose faster.

 

Freak did you go with Pacesetters?? What would be much easier than a 6l90 swap would be a T56 swap.

Can't argue that. But I think it'd be much more fun/satisfying getting the most possible performance out of the same mods. The "fun factor" between a 500RWHP car vs a 500RWHP "Brick" would be no comparison IMO.

 

d**n, I wish my brother-in-law had never let me drive his C6 Vette.

Not everyone can make a mustang fast. Ford has been trying for 40 years and haven't done it yet.

 

 

 

 

 

They could if they really wanted to.

 

And what about the Mach 1...1970-71 I believe? Wasn't a Ford guy in High school, but a friend of my brother's had a Boss 302 which was pretty fast.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.
