    Hello All- New here with a new project!

    Back on the road! Took the used engine on a solid shakedown run tonight after resealing everything. Ran it hard- Hot idle holds at 20psi, cruises at 40psi, and 55psi when it kicks down on 5w30 full synthetic. Runs like a champ. I'm currently regretting not replacing the timing chain while it was...

    Slight knock?

    There was also a TSB I think I remember reading a long time ago that also when I was concerned about this very noise that discussed having to measure and replace main bearings in .001 sizes to correct a bottom end knock (I'm 90% was warranty complaint related)...dont recall the details exactly...

    Slight knock?

    I've owned three of these. All of them had a slight bottom end knock on cold starts. First one had 349k when sold...ran the dogpoo out of it. My dad is still driving one with 250k. I'm currently replacing engine in the third after discovering poor quality rebuild after pulling apart to do head...

    Best Intake gaskets

    I doubt they last also, but gonna give the benefit of the doubt for now...the fiber gasket seems like the way to go on them with sufficient torque. That'll be perfect timing to build a nice little "eco-boost" 5.3 for it. I'll update here and in my project thread when they fail... I've had two...

    Best Intake gaskets

    I'd agree- not an optimal bolted joint design. Guessing they prioritized clampload of the coolant passages when they went to vortec heads which likely had a little more heat in them. Seems like they used the composite gasket to allow for some flex in the aluminum. Ended up using the Mahle...

    Best Intake gaskets

    I know this is a couple year old post, but I wanted to point out a potential issue when using the 1255s for anyone who stumbles on this thread like I did... After a lot of research on what to use on my project, I bought a set of 1255s because it seemed like the logical choice when evaluating...

    Hello All- New here with a new project!

    Forward progress! Engine is back in. Taking some time to repair the tape and cor-tube on the harness as I go...its fairly brittle. Currently at a standstill while I wait on parts. Hoping to have it back on the road next weekend.

    Hello All- New here with a new project!

    I can only imagine...LS EcoBoost! Without the Eco. Just seems like a good idea. You still get the more modern (but aging) FI system, economy, reliability, and power of the LS, and as much power as you want when you plant your foot in it. Loads of real estate to pull it off too.

    Hello All- New here with a new project!

    Updates- After teardown of my peanut-butter filled "original" engine and over-analyzing a boatload of options (LS swap, crate l31, smeding 383, etc) I picked up a new-to-me L31 from a 2500 last week with 150k miles. Seemed to run great...no knocks or smoke and compression galore. Giving it a...

    Smeding Performance 383 in a 97 C1500

    I ask because I'm considering their short block and there isn't a lot of folks out there that have left many reviews. The last couple years have been unkind to engine prices.... Getting dang near unaffordable. Local shop quoted $7500 to completely rebuild my L31. I can get a new L31 long block...

    Smeding Performance 383 in a 97 C1500

    Hows your experience with the smeding short block so far?

    Hello All- New here with a new project!

    Alright- at a crossroads and need some input/advice. I've got my tree-fiddy torn down. Bare minimum shes gonna need heads, bearing set, gaskets, crank polish, etc. Its had a recent rebuild as there is no discernible ring ridge, etc and its 30 over. Rebuilder pistons sit in the hole at TDC...

    Hello All- New here with a new project!

    I also left out that it had the crappy plastic intake gaskets that came apart in pieces when I took it apart. Also very little torque if any on the front two intake bolts...all of the coolant passages were full of stop leak...guessing more likely than not that intake gasket was the problem
