7.4L C2500 GMT-400

[lbmimica]

Hi, is there any C2500 with the 454 7.4L Vortec Reg Cab? I've been looking for one since 2019 and still can't find one. The state does not matter.

If your location is correct and you're truly in Chile, then there isn't much we here in the USA can do.

I see them around this area every now and then. Not as common as the 5.7, but they are still some out there. In this platform, the C/K2500/3500 Vortec was 96-00. Some of the regular cab trucks with the 7.4 Vortec were fleet (work trucks.) White in color with plain interior.

Does it have to be a C2500? They also made C3500 with single rear wheel (SRW). They are pretty much the same as the C2500. I want to say I actually see more C3500 SRW vs C2500. There are also a lot of the C3500 regular cabs with service beds, but I'm not sure what you are using yours for. Tip: stay away from the Northern US trucks if you want to avoid rust problems. Rust is generally not a problem in the Southern states.

Good luck.

hmmm, I'm actually interested in the c2500 7.4L Vortec regular cab for regular cargo work, but I plan to do a project with a 7.4L c2500 in the future, making it like a modern version of the 454SS, but first I need the truck.

What are the main features of the C2500 and C3500 that differentiate them from the C1500? and what are the differences between the C2500 and C3500.

Like this one for example (JUST AN EXAMPLE).

Well, that sounds like a project!

The 2500/3500 frames are heavier and deeper than the 1500. All of the 2500/3500 regular cab trucks were long bed (8 foot bed.) The axles are 8 lug and pretty heavy. The brakes are also robust and heavy. They are basically heavy work trucks with heavy drivetrain...

Are you going to shorten the frame to modify for a 6.5' bed of the SS? What about the 5 lug wheels?

There's really a lot differences between the 1500 vs 2500/3500. You should dig deeper into it. The SS was built based on a 1500 truck, with some heavier stuff borrowed from the heavier trucks.

Not much difference between the 2500/3500 with the 7.4. Same transmission, I can't remember if the same frame (on RCLB configuration), hydroboost brakes, same 14 bolt full float axle. Maybe different brake RPO? Spring pack? Maybe the 3500 frame is a bit thicker wall? Can't remember at the moment.

There's also 2500 with 6 lug wheels, which are confusing. They are closer to the 1500s than the 2500s.

Good luck.

2500 8-lug truck frames are dimensionally similar to the 1500, just thicker.
3500 truck frames are taller
Both can have semi-float or full float axles.
Brakes are basically the same. Steering is the basically the same.

The main difference is the GVWR. 2500's, on paper, legally stop at 10,000 lbs. 3500 go higher. Reason is DOT regulations for interstate commerce start at 10,001 lbs GVW. So a 10k lb (or less) truck doesnt need to pull into a weigh station.

I thought the 1500s had 6" frame, while 2500/3500 were 8" deep?

The 2500 GVWR we're 8,600 lbs.

3500 SRW GVWR = 9200 lbs.
3500 DRW GVWR = 10,000 lbs.

These are late GMT 400 numbers, the earlier ones were a bit different...

The 3500 cab+chasis or 3500 F44 was like 12,000 #, but those frames were different altogether.

Thats some good old information, thanks for that, its much clearer now.



Well, it seems that in that case I would have to shorten the chassis and shorten the bed or replace it with another, my reason for the project is simply caused by the fact that I consider that GM on the 454SS wasted a lot of engineering, first considering the fact that the 454SS had 230 horsepower (it could give a lot more but they just didn't want to take advantage of the engine's potential) it had chassis reinforcements to support the weight of the engine. And finally what impresses me the most is how the 454SS was able to go from 0-60MPH in 7s, which I find impressive considering the low horsepower factor and more or less good torque.


I am currently 18 years old and my father has a Silverado 97 ', it has 255 HP and I do not know how much torque, I also plan to start a project in it to improve it and make it more muscular, but that is another post that I will do in the future.

Returning to the subject, I am quite ignorant to the Big-block and that is why I would like to investigate more in that world, I consider that a Vortec 7.4L 290Hp engine has a lot of potential to give better, but Chevrolet did not care about the speed in At the time, Chevy cared about torque and quality, which is why I like these trucks.
