20 mpg city and 21 mpg highway? 11.99 in the quarter? First off stock those trucks might get you 18-20 mpgs tops on the highway with maybe 14-16 mpg city. On top of your outstanding fuel economy I highly doubt a truck with well over 500 rwhp is gonna get that kind of fuel economy, I mean to do 11.99 in the quarter mile you need at least 500 rwhp or so. Hopefully you are talking about a truck you did heavy modifications to cause a stock engine and transmission certainly isn't going to get you anywhere near 11.99 in the quarter mile unless you mean 11.99 minutes. The 350 is an excellent engine, but your story is just way to far fetched.

The quarter mile times that you speak of is outrageous. My friends 1988 Silverado was slower than a Lumina another kid owned. In order to run 11.99 in the quarter mile with my 1981 Corvette I would have to knock a good 2 seconds off my quarter time. And the gas mileage is crazy too, my dads 2000 Silverado gets about 18 mpg, and its gets much better mileage than the old Silverados.

I have to say that the truck does have a lot of power. I watched my husband pull a semi with his 2 wheel drive extended cab long bed. For a 2 wheel drive that says a lot. I can also tell that it does have a good ride for what it is. We have a 93 Grand Am all macked out and you really can feel every bump in the road.

All I wanted to say is that I hope the truck I just bought is anywhere near that. I just purchased an 89 Silverado 2-wheel drive that only has 90000 miles from a friend of my Grandmother. I've always loved the Chevy 350 and feel lucky to have found a 15 year old truck with such low miles that has NOT been abused. Here's to reaching 300,000 miles!

There is no way your truck can run a 1/4 mile in 11.99. a ford power stroke beat a new corvette in 12 seconds flat.

I believe you about the ride I just bought one. The interior or seats are comfortable! there's no way a ford can beat a chevrolet. Found On Road Dead!!!.

Well I dunno about the smoothest ride, but for a truck with a 2-4 drop and posi, which I installed myself, it rides pretty decent. But y'all are also right 11.99 in a Silverado? I'd say at least 475 rwh and some slicks..

How can you be running 11.99 in the quarter when I have the same exact truck as you do, with short tube headers, cold air intake, rebuilt transmission with b&m shift kit, and I'm running high 17s in the quarter. There's no way you're running 11.99!!!

Well we have used our 1989 Chevy for 9 years, and in that time we got a best mpg of 17. There is more to a time than 11.99, I would bet that is actually an 1/8 mile track. That's what we run and our truck is a rather sleepy 13.5 sec. The weight, power, gearing weight distribution and suspension are not good for much more. We run a 1973 Chevelle that does 11.83 in a true quarter in the 1/8th that is a 6.98 car. So, let's get some real numbers and more down to earth claims.
I am just trying to help you out in relaying your love for your truck. I would never trade mine, even with the 364,871 miles it shows. Just enjoy it and keep it real. Saturday morning car shows always leave things out, so let them tell the tall tales. And above all else, be safe with your trucks!

Besides that, Ford stopped putting the 5.6 liters in after 1996; the biggest engine you can get in a 1998 F-150 was a 5.4 Triton.

Actually, the Ford motor you are thinking of was the 5.8, or 351. Ford never had a 5.6.

I just bought one off a guy and I like it. The 89 has always been my fave. So just keep it real and roll on.

More power to you if you run that. I don't believe it, but it is possible if you do the right tweaks. I run a 12.5, but my truck has over $22,000 under the hood let alone the transmission. You might think I'm crazy for investing that much into this truck, but it means more to me than just a truck. It was my baby brother's truck, but he died saving me from a drive by shooting. But anyway. This guy's mileage could be correct with the right tweaks, anything is possible. Why does it matter what the Ford has for an engine? Fords straight up suck. LOL!

Take the cat off of the truck and that is the fuel mileage that it will get! But the quarter mile time is bogus. Stock, one will run 14's.

I have a 1989 extended cab and I'm in the the middle of assembly. I'm going with the Edelbrock 3702 cam, double roller timing chain, port and polished heads with bigger valves, spacer plate for throttle body and headers with true duals and also a jet stage 2 chip. I'm hoping it will be around or over 400 horse. After break in and some tuning, I'm going to take it to the track to see my times.
