Between that and the intake it should be pretty nice. The compression ratio for the gas engine is 7. It produces 240 foot-pounds of torque. Also size of the pipes probally need atleast 2. DrivetrainThe 1990 Chevy pickup was equipped with a standard 4. You pro'lly know that since you race- dumb me Another help might be a fuel pump upgrade if you think the engine is starving for gas.
Thermoquad version or the Q-jet version? Having said that I have a friend that did something along this line that was really different and that I really admire. Matt What kind of edelbrock carb is it? Nothing I done changed gas mileage. As for the truck, when it hit 100,000 the thing started having problems. I metered them both and they are different resistance. The truck was great but becoming a money pit. An 88 454 is a pretty weak motor, powerwise. A few years ago my dad swapped in a 5-speed stick after going through 3 transmissions in less than 75,000 miles.
No distinctions are made regarding the model of the C3500, including its drivetrain rear-wheel drive or four-wheel drive or size regular, extended or crew cab. I am in no way saying to replace these or they are the exact reason. After breaking crankshaft I destroke to 427 aluminum heads n trying 200r trans. Torque for the engine measures 360 pound-feet at 1,700 rpm. Of course, that could also be because we just got done with harvest, and using an F-350 V10 six-speed with 4. BodyChevrolet built the 1990 pickup with a standard two-door cab and an optional extended three-door cab with a bench rear seat.
Having said that I like this truck. His talent for boiling down events to such a painful truth, much to the chagrin of the idealistic ninnies surrounding him, did give him an engineer flavor. I got the yoke on the driveline, and it was the perfect length, no modification besides yoke needed. Anyway, plenty of people have done it and I haven't seen any failures in my research. He had a Ford302 and C6. Some might even call it overkill.
And I have to say, feeling the rumble of the 12V Cummins and hearing, on the edge of the human threshold, the near-ultrasonic whistle of the turbo spooling made this young man a minor diesel-head. At its peak, the 454 was developing 450 horsepower in the Camaro and Chevelle passenger cars. Blow air into the tube and listen for a bubbling noise to ensure. Overkill is also a relative term. I always tease him about his King Kong engine; he said it gets about 10 empty and maybe 9 loaded.
It also has a newer 750 edelbrock carb and dual exhaust with glasspacks. Maybe start putting it back together. That is the hot commodity in the coming decade. I ended up sliding back the existing trans crossmember and mounted the trans to that. Still uses a lot of gas regardless. These 454s with four-barrel carburetors developed 230 horsepower and 360 foot-pounds of torque.
My feelings about them today are pretty much the same. Frank My 92 dually is the same as the rest reported: about 12 on highway, 8 around town. Several focus groups indicate pickups are the future hot commodity in the coming decade. It was a solid 6 mpg from the day it was bought new. I always liked driving it, especially after the engine work.
Webster defines overkill as: an excess of something as a quantity or an action beyond what is required or suitable for a particular purpose. Low pressure will degrade gas mileage. A manual trans Impala would have allowed some Corvette like performance stick, engine etc while taking the family out. I think we have found the reason U-Haul liked these engines. Of course, pickups do tend to get worse fuel mileage. Strangely, me with my cushy Olds V8-powered Buick, I never took much interest in the truck.
I drove the van I took the engine and other parts from since it was new and it didn't lack in the power dept. Admittedly I am no expert in 90s engine design but I think all of the engines were choked down quite a bit. I did however get the wiring harness ran through the firewall and started laying out locations for everything. He had it until 2010, when the transmission failed at about 250,000 miles. Sure, even then I knew it was odd, possibly rare, but other than that it was just another truck with a big block. Or at least 10 empty. I haven't checked it myself yet, but I think he said it's up to around 8 or 9 mpg now.
