    My 454 Rebuild

    Don't forget you will need a transmission controller if you switch to carb.

    k2500 8600gvrw trucks tow ratings have gotta be under rated

    You may be right. A lot of things can come up when you are right at the edge of your ratings. I looked up your trailer because it was curious. It's a monster for a conventional trailer! The "dry" tongue weight is 1250 on forest rivers site! Thats 15% of the "dry" camper weight of ~8500lbs...

    1984 350 block with vortec heads

    Built most of my engines this way. Clean up, check guides, lap valves, new seals and springs. If things don't check out (warped deck, bad guides, bad valve seats), then get a machine shop involved.

    k2500 8600gvrw trucks tow ratings have gotta be under rated

    To some extent, GVWR is a made up number anyway to force vehicles into a specific registration class. Manufactures play with these all the time to put vehicles in the class they want. Your GAWR front and rear tells the truth on payload. My Suburban is an 8600gvw truck. But the front axle...

    k2500 8600gvrw trucks tow ratings have gotta be under rated

    The ratings are a little odd. But the lower rated trucks where the 5.7 trucks. My towing experience is all with a 1500 350, so a little different. But the same rated power, so I can speak to that. But I have done a LOT of towing with our old truck. The 350 is a great engine, but stock you will...

    k2500 8600gvrw trucks tow ratings have gotta be under rated

    Just ordered on for a 2500, it was a 2 3/16" thick 2 core 19x34. I looked up the 3500 as well and it was the same radiator. I thought you could get the 350 trucks with a FF rear...maybe that is only in the 3500's. There are so many combinations on these trucks its hard to keep track.

    k2500 8600gvrw trucks tow ratings have gotta be under rated

    Cooling systems and power. The 454 trucks were rated to bumper pull 10K if equipped with 4.10's. 8500 or so with 3.73's. 350 trucks had the lower 7500 rating with 4.10s, I believe. The only major difference between the two 2500 trucks (if both equipped with 4.10 gears) is the radiator, and...

    towing with a k2500

    I have a 4l60e. It tows my camper for hours at a time in 3rd. As long as the converter stays locked the trans never exceeds the engine coolant temp. 185F in my case, because my thermostat is lower than stock. I do have the "tow package" with factory external cooler. Without an external cooler...

    Need a new Y pipe..

    I have a Jegs mandrel bent catless one on my truck. Pipe was great, gaskets and clamp that came with it sucked. Replaced those and now it's leak free and fits great.

    towing with a k2500

    Thanks. Cheapest money could buy on amazon! :) But they work great. Wanted factory style tow mirrors but they were more expensive and lots of reviews complained of vibrating mirrors. I prefer the GMC grill as well. We have towed with this setup all over the place east of the Mississippi...

    towing with a k2500

    Yep. I have monitored mine with a scan tool. The trick is to try to keep the converter locked. A short time unlocked is fine, but if I am going to be pulling a hill for a long time, I will back off the throttle until the convertor locks back up again. The temps always stay stable if the...

    5.7 from 99 GMC Yukon having heat issues

    If it is overheating at highway speeds, then its not the fan. Assuming the water pump doesn't have a mechanical issue and there are no air pockets in the system, it is flat out not enough air flow through the cooling stack, or not enough cooling surface area. Do most v8 swap guys use that 4...

    towing with a k2500

    I tow a 6500GVW camper with a 1996 1500 Suburban. 4 people and all our stuff. We have even done 6 people, but that was only down I95 on the east coast. Not as flat as you would expect, but no huge mountains either. 3.73's and tow package. It does the job. I lock out overdrive and set the...

    GM crate engines?

    I don't think that is the case. GM says you can run the HT383 on the stock tune. You can change your exhaust without a tune. Optimizing the tuning helps even on a stock engine, but it is not required. Definitely not required for the possible 5-10 cfm difference (if that) in flow on the...
