Hi guys,
Some of you are aware that I'm in the market for an FE or FC up to $10K. No luck so far. But in the process of hunting, I've come across an issue I need some advice on. I'm looking for something that's been modified. I've always thought in terms of a 186 or something similar as replacement to the old sideplate. But I've seen a couple of cars that are running small V8s, and one of them was on gas. Just on a fuel economy point of view, what kind of mileage can I expect from a small block V8 on gas? (and can you talk to me in mpg, I still can't get my head around km per litre)
Thanks for your help,
Rev
Hey Rev,
not sure if V8 and economy belong in the same sentence..
not so bad if you have a light foot i spose, good gearing, overdrive, and EFI...
figure on 16 - 20L/100kms (city)
or around 15L/100 (highway).
that's with a 1.00 final ratio on gearbox, 3.25 diff gears and EFI.
im fitting overdrive to reduce the consumption and adding a lock up convertor.
sorry about the L/100 thing, i cant get my head around MPG.
hope this helps.
these are petrol figures, LPG uses about 20% more.
if you're in the marklet for a V8 have you seen Ben's (revhead fc) 350 HR for sale?
Cheers
Ed
G'day Rev,
Was always keen on running a carbied small block chev in my fe but excessive fuel consumption killed that idea.
Changed the plan to an injected 5 litre holden with a 4l60 box ( about 30% overdrive).
I am running 2.75 diff gears with 13" wheels which brings me back to about 2 grand at 60 mph with the o/d auto. Pretty close to standard commodore gearing.
With any luck we should get somewhere around 32-34mpg out on the highway which will work in with the plan to use it as a daily driver if need be.
The engine is stock bar the addition of a factory 195kw VS HSV chip and a very mild camshaft chosen to suit it.
Minus power steering pump and with a decent exhaust should get a bit over 200kw and a shed load of useable torque.
The extra initial cost of an injected engine will soon repay itself in fuel savings if your'e keen to run up a few miles.
Injected engines are becoming real cheap these days, a vn 5.0 L went for $900 on ebay recently!
Cheers, Rob.
