Agreed. The LS is superior as far as factory power, injection, availability and affordability!Yeah but, an LS is not a 350 and never will be.

Where the old 350 is better, is, low end torque, and longevity. Keeping in mind that the 5.3 was GMs choice to replace the 350 with. I have had my 97 with a 350, 5.7L Vortec for 20 years. I could always out run a stock 5.3L. yes, the LS is the most popular engine swap out there, hands down, and is also the most supported engine swap out there. Yes, it is easier to build a LS and make power with it, but if you want a LS powered vehicle, why are you even fooling with a GMT 400. The LQ9 SS Silverado is a very nice truck, IMO. Or go old school with a 1950s or 1960s truck and LS swap that. Part of the grateness of these trucks, is the 350. The fact that it is the last of the 350s. But hey, in the end, the choices are all up to the owner. We can all do whatever we want with our own trucks.Agreed.

I agree. The 350 is an amazing engine and there are still a lot of aftermarket and junkyard parts to be had for them.Where the old 350 is better, is, low end torque, and longevity.

I think he meant wiper motors.I doubt it but I’m a Honda tech not a GM. I know you can still get new GM engines.
Let me throw my $0.02 into this discussion. When my 88 C1500 5.7L TBI blew its head gaskets, I looked into Vortec and LS swaps but, decided to see what fun I could have with TBI. Yeah it cost more than a JY LS swap but, I wanted more low end torque and better power throughout up to over 5 grand. I'm happy with the results running on a bored 4.6mm TBI (among other go fast stuff) AND old school EFI that tunes itself 200 times a second as opposed to once a week with a toilet bowl on top. It's an electronically controlled toilet bowl which starts and runs fine in different climates and elevations Plus I don't have to pay for any credits or such to tune it!But in my opinion, the LS is no less reliable. And I love the GMT 400 for many reasons. It’s just crazy to me that it’s so much easier and cheaper to get real power from them with a carburetor than with the factory fuel injection.
Again, the fun part is doing your own thing and something different than what you’ve done before. This Vortec build I’m currently doing is fun for sure. But also pricey. So my next build will probably be an LS!Let me throw my $0.02 into this discussion.

OK, I'm getting off my soap box now
What did you spend your money on? Roller rockers and a $500 'hot cam'?I’m $2500 into my 350 Vortec already and that’s only to get it to around 300 HP.
no.What did you spend your money on? Roller rockers and a $500 'hot cam'?
