Fuel mileage poll

[Willowbilly3]

What engine trans combo would you say to be the best on fuel mileage. for the sake of argument, lets say it's going in a basically stock mid 50s pickup body, and it's got to be a V8 and automatic.

Anything except a 350 Chevy.....love em, but they're the worse for good mileage, I know I've had quite a few!. I would have to go with a Ford 302 and any type of Overdrive trans...CR (This should get real interesting WB!)

 

[TiredIronGRB]

283/327 have anyways been a good power/mileage option.

 

[rustybeercan]

Don't forget the rear end as well. That also dictates mileage. I prefer OD trannys too.

572 and tremec 6 speed.

 

[HOT40ROD]

Also depends on the rear end gear ratio and tire size.

My blown 454 gets 14.3 mpg on the hwy @ 65 mph , my '93 Z-71 gets less, why , I wish I knew !

I used to get about 19-20 on the highway in my '57 Chevy with a 327 and 4 speed until I went from a Q-jet to an Edelbrock. I get about 16 now. An overdrive trans and good gears should get about anything decent mileage, regardless of brand.

 

[Willowbilly3]

Assume optimal gearing, I'm not looking for a discussion on gear ratios. I'm just looking to discuss engine/tranny combos here. The cruising rpms would be worth mentioning tho. Personally I have had the best mileage from 283s and 289s but mostly stickshifts.

The carbed 350 with 4 spd in my 70 C-10 does better then the tbi 350 with a 5 spd in my 94 GMC did. Alot of factors dictate mileage more than just what type of engine.

350 sbc 700R4 w/ 3:42 gears in an S10 blazer knocked down 17.5 mpg's. TPI 350 in a vette 700R4 w/ 3:08's knocked down 23mpg. 5.3L vortec with a T70 turbo, 4L80E and 3:23's in an 89 C1500 made 12 mpg @680 crank hp. My 325hp 396 th400 3:90 geared chevelle is 8-10 mpg at best. [P

 

[lowbuckrats]

307 sbc w/ a 700r4. Stock aluminum intake with a late model non electronic Quadrajet with a summit R/V cam. I got 20-25mpg all day long in my old 60 Biscayne w/3:55 gears. OD+long stroke motor=torque=good mpg. Had great power too...I miss that car...305 should do the same, but I think the 307 is way better.

What does fuel milage have to do with hotrods?

 

[Crossfire]

fuel mileage

Really depends on what kind of truck its going in too. If you want mileage Chevy 307 0r 305 with t-5 tranny Ford 260 or 289 with t-10 tranny Mopar 318 with A833 -4speed overdrive.

I'm just wondering why we are talking about gas mileage with are toys. To me its about horse power.

There can be a difference between a hot rod and a cruiser/daily. [S

If you like driving to long distances, it matters. I would have loved to have driven my flatbed to Bonneville last summer, but I couldn't afford to do it. I drove my Toyota there for 1/3 - 1/2 the cost.

The 41 dodge truck is going to get a sensible drivetrain....and air conditioning.

My 3500lb AD pickup with a tired,flat cammed 305 with a Rochester 2 bbl carb and Turbo 350 got 18 MPG. I rebuilt the engine with an RV cam, SP2P manifold and Edelbrock 500 cfm carb and the best I've gotten is 16.

For some of us they aren't just toys but also daily transportation. The difference between 5-6 mpg and 15-16 is enough money to buy a lot of parts if you are driving 1000 miles a month (about average for me)
