Whats the difference

175

Asked by Aug 14, 2014 at 05:03 PM about the 1999 Chevrolet Silverado 1500 LS Standard Cab LB

Question type: General

I have a 2004 Chevy TB with a 4.2 inline 6.
I have a 6x10 trailer (a high one with 6 feet 3 inches of interior height) that I was going to pull behind it.
I don't believe my TB has the balls to do so and not do damage to it. But I may be wrong.
I'm thinking of getting a 1999, 1500 standard cab with a 4.3 v8.
I was told that even though the size was close, the truck would pull much better.
I'm wondering if this is the case or not, and why?
If there is no difference then I'd go to the 5.3 and leave it at that.

The in line 6 is mostly a torque engine, usually low speeds, not good for highway speeds much above 55 mph unless you have the high geared trans and rear end then it's no good for hauling. The 4.3 will have better pulling power at the higher RPM's on the highway so you could use a lower geared trans and rear end for better pulling power. The 5.3 will have the best low and high speed torque for towing, but of course you are trading power for fuel economy, the more power the less mileage per gallon. HTH

Thank you very much. That explains why when towing the empty trailer home from the mfg. I could go down to 3rd (out of OD) and it would pull fine but ate gas like a fat kid in a candy store. I guess with something under 3000 pounds GVW, the 4.3 V8 will be sufficient? Am I right? I don't mind going to the 5.3 but only towing 1 or 2 times a week, locally for 80% of the time. Thanks, your info was really useful in terms of understanding two engines so close in size yet so far apart in performance. Stephen FORE! Play Golf Smithing

The 4.3 should work if it is like you say just local, check around, see what kind of trans and rear end ratios are available, you don't want to go too low or you will loose mileage.

the 4.2 has more power than the 4.3 (the 4.3 is a v6). The only thing going for the silverado is that its a full sized truck. Both are technically a 1500 anyway. All that matters is the gears in the rear. Which ever has the better gears (higher numerical value) 4.10 would be amazing, 3.08 would be crap

My mistake. I'll stay with looking for a 5.3 V8 then. I don't mind sacrificing some mpg for the correct sized engine to pull my trailer, even though it is a relatively small cargo unit. Thanks Stephen

4.10's I made that mistake once, true you could climb straight up if it could get traction but your mileage will be horrible, the best I could get was 9MPG, got some 3.75 gears for it and my mileage improved to almost 14MPG, 13.8 to be exact, and my power was not that greatly reduced I could still haul my fully loaded trailer that weighted out at 10K loaded way back into the hills, and still make highway speeds.

maybe I was a little over enthusiastic with 4.10, I believe chevy makes a 3.73 that would be great. 3.42 wouldn't be too bad either. Any less that that and it's not good. The 5.3 is a good platform, you mileage wont suffer much and the power is defiantly there.
