lol

Just a seat of the pants.

The 08 5.3 Sierra with 80,000 doesn't have what the 04 Suburban 5.3 has with 190,000

They are very hit miss, on "feel". Also believe the suburban have less tq management than the pickup, so that makes a big difference in performance.

I know there's a lot of love here for an old school carbureted sbc, and I'm also a fan, but when was the last time you guys saw one that went 3-400k miles without a rebuild? If the oil is changed every 5k miles on these vortec (or whatever they're called since 98 or 99) they'll outlast 2 or 3 bodies. Imo, they'll damn near go forever with simple maintenance. 350's needed a cam every 60k

Muh hewo....

The 95+ truck small blocks seemed to have good longevity. I have tore plenty down, and very little ring Ridge after 150k+ miles.

The old ones showed a Ridge well before 100k if they were still running lol

Have seen numerous 300k+ 4.8,5.3,6.0

427 4 speed!





It's fun to think about....

If it is going to be a toy, go for it. If you want to use it.... No

Sorry. I know it was fun, but any sort of current efi is better than a quadrajunk.

6.0 's probably aren't everywhere, but maybe you could find one. 5.3's though are plentiful. You're used to the 6.0 only hitting on 7 anyway. Look into what Joe mentioned earlier about a 5.3 conversion.

I was looking around a bit and found a few 6.0's with around 120-150k miles asking 1,300 to 1,900.

The toy vs driver thing...

Mike needs a tj wrangler. Stuff a 427, 400 turbo, d60 rear, 8.8 front in there. Go have fun. Tow it around with a 6.0l 2500hd....

 

[jake wells]

just replace it with a used 6.0 and call it good.

OK. I was thinking the variable displacement GM started in '07 5.3's

Neither have traction control. I believe the Sub has 3.55 and the Sierra def has 3.73

Dang. I figured $6-800. Probably find a 5.3 for $400.


If you're up for a real challenge (and numerous ulcers from OD'ing on headache medicine), there's a 6.5 turbo with 70k on it in my backyard. Your's for the asking.

 

[czar800]

The simplest thing to do is drop in another 6.0 and be down the road. It's my work/farm tuck. I really don't have anything invested in it yet so it's worth fixing.

That motor had a tap eight years ago...(that's when I started) and who knows how long before that.

Save the 427 for a older more deserving truck, maybe a 69 or 70.

That was just a quick search, I make some phone call over the next few days.

Thanks for the offer, but I truly have a shop full of projects and the fact is this truck it's very high on the list. Spring is coming and all the repairs I was going get done over the winter never happened.

Agree 100%.

Motors are less expensive here. I can buy a complete (what's left of it) '00 2500 reg cab long box for $2-3k.

Also, I'd wager a guess that your jasper trans is possibly the best upgrade that truck could have. 4L80's aren't gm's strong suit. My 93 slipped at 2.5 years old. My 95 dually had the trans gone through twice. Not a fan

 

[Dub11]

I would consider pulling a 366 or 427 from a old school bus.

427 4 speed!
I got a sm465 ssetting in the shop now?



It's fun to think about....

 

[Dub11]

Or just go back to stock

 

[Dub11]

I have a 4l80e in my 91 sub of course the 350
in front of it aint no powerhouse ether but it does shift good.

 

[Dub11]

And its an old state truck 221000 miles

I was going to say earlier, the bodies and frames here usually last twice as long as what you mentioned and people usually go through two motors and trannys because of the heat. just my guess anyway, in order to reach 300-400k
