6.2 swap thread

[ls1frc]

I think I got a winner on the oil to make my cold starts sound less like my engine is completely broken.

Swapped in Castrol Magnatec synthetic. The marketing hype is basically it will cling to your parts better and give you better cold start protection. I have circulated it through about 150 miles and today it was 15 degrees out, but was the quietest cold start I have had yet. It still sounds noisy, as any engine would, but the terrible lifter clacking wasn't there. I am going to add liqui moly MOS2 additive to it to see if I can get it even quieter.

I'm running Royal Purple 10w30 HMX and a QT of the Lucas syn oil additive. Nice pressure and no valvetrain noise

Figured I'd update...

About 2000 miles since the swap. No issues to report. No oil consumption, no leaks, no odd noises, decent fuel economy. It just sounds pretty bad in sub 40 degree temps, but whatcha gonna do. The magnetec oil definitely helped here. It used to misfire when it got cold, which it no longer does. I assume from the lifters bleeding down and taking a bit to re-engage with the pushrod properly until oil thinned out.

Sounds insane at WOT. If this snow ever goes away, I will take a video.

Can't wait to see that video.

No, all the original 5.3 stuff is off. I use the Kooks 1 7/8" headers to a 3.5" y-pipe to the Corsa Touring 3" exhaust.

I bet it sounds like a BEAST!!

The Touring + Vibrant Resonator with headers is about the best combo possible for a street/family truck. Sounds very quiet 3k and under. Absolutely screams at WOT.

It droned with the 5.3. The 6.2, I guess because the additional torque down low, has no drone.

I have a 50k mile l94 engine harness. Any recommendations on where I should list for sale and how much?

Marketplace has been decent lately.

Uncut, advertise $200 and take a $100 cash
