    towing a 2door civic on a uhaul flatbed

    Ran into that issue towing a full size G20 van behind a 2011 Pathfinder. Pathfinder has a 7,500 lbs tow rating and the V6 had plenty of grunt, it stopped and steered well enough with trailer brakes but it wanted to sway around 55 mph. Just took it slow on the back roads at about 45 mph and no...

    towing a 2door civic on a uhaul flatbed

    About 15 years ago, I towed an enclosed tandem axle trailer at about 5,500 lbs to Denver from Texas and back with a 200K mile carbureted 1983 G20 van that had a 305/700r4 and 3.08 gears. No problem doing it albeit was slow uphill. Just manually shifted it down and stayed out of the secondaries...

    The 108 LSA in that cam helps it keep most if not all the stock low-speed torque of a L31. Its a shame that GM has it priced so rediculously high now. 24x is a nice upgrade too

    Rear Diff Cover for Cooling..

    Wish banks made their cover for the 10.5 as I would own one but they only do them for the 11.5. After 2 hours towing the travel trailer the 10.5 was running 275°F prior to the large finned cover. Dropped 50°F with the cover and added fluid.

    Rear Diff Cover for Cooling..

    A 12ft utility trailer is the only thing it ever towed with the 8.5 still in it. Maybe 3,500 lbs behind it max. It was overheating the fluid moving only the van. Then again it was a good 6,200+ lbs empty and often got cruised at 80-85 even 90 mph in the middle of Texas summers on a 105°F day...

    To LS or not to LS, that is the question

    4 door LT model. Engine came out of an Express van and has the mercruiser 496 mag HO 425 hp cam and headers. Currently have the 8.1 engine on the stand in the shop, waiting to me to finish the Express van and put the 8.1 back in the Tahoe. Started loosing oil pressure a year ago. Bearings were...

    To LS or not to LS, that is the question

    ALL the 24x systems have the cruise wired directly to the TAC module with no can bus. 99-07 24x engines.

    Rear Diff Cover for Cooling..

    More fluid is helpful in controlling fluid temps. When you are flat out like climbing a mountain the fluid itself stays at a lower tempetature during the load spike because of the extra fluids mass and its ability to absorb more heat while staying at a lower temp. Then when you are off the...

    Rear Diff Cover for Cooling..

    I think you would. be surpised just how much airflow is there even without directed flow. I popped an input shaft seal in the Express shortly after I put the 4L85E into it. I was rolling about 50 mph. I coasted about a half mile before I could get off the road. I had a huge smoke screen...

    Well if it was overworked it was a GM fault as it was a stock setup at the time that did not have a hitch. It was turning the fluid black even at low mileage when it still had a stock engine and 4L60E. Never made any noise until the spider gears grenaded.

    Rear Diff Cover for Cooling..

    I broke the spider gears in the 8.5 that came stock in my Express van shortly after swapping to the 4L85E and starting to tow with it regularly. When I tore into it the spider gears were the least of my worries. The axles, axle bearings, pinon bearings and ring and pinon were all blue from...

    Rear Diff Cover for Cooling..

    Nissan recalled the Titans in about 05 or 06 built prior to that point and switched them from 80w90 and a stamped steel cover to the finned aluminum cover and 75w140 synthetic oil. Dodge also recalled my 2006 Ram and switched from 80w90 to 75w140 when it was about 1 year old but no finned cover...

    To LS or not to LS, that is the question

    I am of the opposite opinon myself. I find the DBW easier. I did a DBW LQ4 swap in a fomerly 305 TBI 87 G20 van. I ended up using a pedal out of a chrysler hemi application. Electronically it matched with the 05 TAC module. Hooking up the cruise was a 3 wire connection and the 87 vans stock...

    Near-factory AUX switch

    Vans have a rear blower switch that could select between about 3 outputs.

    E-Force Supercharger 1552

    413 and 440 were both a great RV engine and a smooth running torque producer for those massive 300s and Imperials.
