More Power and Better Fuel Economy Thanks to Tuning and Overdrive! Ep.71

Square Force 1 is my 1989 GMC Sierra R30 cab and chassis square body truck that was converted for enclosed car hauling duty over 30 years ago. It's powered by a 454ci V8, which is backed by a Gearstar Performance Transmissions Level Four 4L80E tranny and a Yank billet converter. Prior to swapping the original TH400 three-speed transmission with the new four-speed, the truck averaged 5.5 mpg during a 5,300 mile coast-to-coast road trip. During this episode we'll address some tuning issues with the 454 and then road trip the truck with the new trans. After the mods the truck nearly doubled it's fuel economy; We achieved a best of 9 MPG and a worst of 6.5 MPG. This video will show you how to find Top Dead Center on a four-stroke engine, how to diagnose a malfunctioning vacuum advance distributor, and how to read the timing mark on spark plugs. Hopefully you learn something or just laugh. Thanks for watching!

I’m sure the flat bill hat gets less MPGs than a rounded bill hat. Maybe if you tuck your ears in the flat I’ll, better MPGs.

GEAR HEAD YOU NEED. 4 .10 WITH CUMMINS WITH OVER DRIVE WILL GIVE YOU 72 MPH TOP END 3.73 WILL GIVE 82 TOP END I CAN GIVE A LIST OF EVER PART YOU NEED TO DO A CONVERTION ON THE CHEV CUMMINS AND EVER THING IS STAND PARTS YOU CAN GET ANY WERE. I CAN PUT A CUMMINS IN THAT TRUCK IN 2 DAYS READY TO TOW. A QUITE FUCK WITH THAT WEAK GAS POT

GEAR HEAD HERE put a Cummins in it I have done many install the CUMMINS with a MANUAL IT WILL PULL HARD AND GIVE YOU.BETTER MILEAGE. V8 GAS RODS ARE TO SHORT TO MAKE MUCH TROQUE. A V8 DIESEL HAVE THE SOME PROBLEM. CUMMINS HAS HIGH TROQUE AND LOWER HORSE POWER. HP BRUNS THE TIRES OF YOUR HOT ROD. CUMMINS HAS THE TROQUE TO MOVE A HEAVY LOAD LIKE YOU ARE PULLING AND TRYING TO GET SUM MILAGE AT THE SAME TIME GIVE THAT WEAK ENGINE TO SUM ONE NEED A CAR ENGINE YOU NEED A REAL ENGINE THAT CAN PULL A REAL LOAD I RUN A 12V.IN MY OLD.CHEV WITH 35 PSI BOOST. GET A REAL ENGINE. TROQUE MOVES A REAL LOAD

This thing has the aerodynamics of a BRICK HOUSE. If you want to improve mileage for relatively little money consider adding AIRTABS (see airtab.com).Those are vortex generators that will improve aerodynamics greatly. Also add some quarter sectioned PVC pipe to the front corners of the box. These improvements will pay for them selves quite quickly indeed. Make a video about it! It'll be fun!

The quadrajet carb needs to be junked and replaced with a nice Holley EFI, perhaps a sniper. Then the fuel econ should increase even more.

Had a ‘’47 Hudson with FE390/C6 and it got 9mpg and didn’t have a lot of power or good acceleration. Repaired vacuum advance, installed advance curve kit, set timing, tuneup, jetted carb for elevation and got a best of 16.8 mpg and had a lot more power. Loved the car all over after that.

Id like to see a video if there is one where you installed the gearstar transmission. I had this same set up and had the electrical system modified for the upgrade from the th400 to the 4l80e for a 4th gear and more mpg. But i never made it happen.

What's the fuel tank capacity? I know older GM fuel gauges aren't all that accurate sometimes but just over 9 gallons at half a tank? Either a pretty small tank or that gauge is seriously off.

Quit crying like a girl about the truck. You bought it. A real man doesn’t buy a vehicle then complain about it. That’s what females do. Nobody forced you to pay the asking price. I wonder if the previous owner you have been dogging for a while knows you will be in Cincinnati for a car show? I also wonder if he were to confront you would you talk about it to him or run like a girl and tell security to take him out. I’d say the latter.

how do u run a 4l80e on that?? trans controller? i have a 89 dually tbi with a th400. debating if i swap it to card and or add overdrive because its having a lean condition. just re did the trans and intake gasket oil pan new manifolds deleted the smog still have egr. now have a lean conditon. maifolds got cherry hot and smoked the wires. dropped the timing to 8 degrees from 10, runs better but falls on its face. think its a timing issue. going to swap in a new o2 and tps and see whats up . has new plugs cap aand rotor stock base half of the distributor

That's pretty awesome but I bet that low compression 454 would like timing more up around 34 or so total mechanical. HEI's are so easy to modify. I grind the tips of the weights with a little curve and then get a recurve kit and put in the light springs. The HEI in my GTO has 25 degrees of mechanical advance and has run it's best E.T. with the initial set at 12 degrees. If you get some more advance I'm betting on 10 or 11 mpg with that excellent 4L80E!

What if you put a Cummings 12v in it with automatic transmission would you get better fuel economy? If you only got 9.2 miles per gallon on the gas engine with that new transmission how about cummings diesel engine automatic transmission an engine swap?

You should look into some kind of wind deflectors to put on the back of the box. Some of the trailers I haul for my company have them and it makes a noticeable difference in fuel economy.

What the hell? Almost 9 mpg in a 40ft long brick that's probably 8 tons loaded with a carbed big block and straight 80's factory setup other than the overdrive and distributor but that's still basically 80's tech. And I get MAYBE 1 or 2 better in this damn 01 6.0 with the same 4l80e and unloaded. Other than the 10 gallons of water I have to carry til I finally put a radiator in it. Already had to do a water pump right before the cap cracked so not getting in a hurry. I don't know what GM did with these first gen vortec 6.0's but they suck on mileage.
