Hey I saw this engine once in germany in a historic museum. do people really still drive arround with something like this? Hey I bet the mechanics for this engine are also good at changing horse shoes
to the people who say they cant afford the spark plugs.....i just changed mine with OE plugs and for 16 plugs cost about $35 so don't give me the shit that you cant afford them...and as for the people saying the new HEMI not making near as much power is because in the 60-70's it was a 426ci now the base HEMI is 345ci big difference in cubic inches...now if your talking about the 6.1 you will have somthing to argue about!!
i have a hemi, 04, excellent motor, 0 problems, i do the work myself, modded at over 400hp at the crank, yes ive had it dynoed, ive had my hemi for 3 years and the only thing ive replaced is the transmission. I work on cars all the time and i can tell yall from first hand experience, i have two be friends with chevy silverados, ones a 5.3, the others a 4.8 and those pieces of shit fall apart all the damn time, they got less miles than my hemi and already the cylinders are misfiring...
@peanuts2105 I know... And they still call it the famous american "HEMI" while the rest of the world built engines with hemispherical combustion chanbers long before the americans did! It's funny.
the people that bitch about the two valves per cylinder are just mad because other companies have to have more just to match the power and if its so heavy than why does it get 28 MPG with the 300C and 21 with the new 2009 Dodge Ram its actually very smart GM and Chrysler are the only car company that have a
just because it is cutting off cylinders doesnt mean it is more efficient...its still using the same amount of fuel per cylinder per mile. so cylinder deactivation does make ur car more economical but the engine itself is not efficient by any means
efficient would mean the same as economical in engine terms and yes it does make a difference if four of the cylinders are off than the engine will use less gas because gas is only going to four cylinders not all eight so it does make the engine more efficient.
yeh i see what your saying..my point is though that instead of something like variable valve timing this cylinder deactivation does not make the activated cylinders more efficient. so its "not heavy" because half the time your driving a 4 cylinder or what i like to call a semi hemi.:P
most companies Put more valves per cyl because it makes the engine quieter and improves gas mialge and they new hemi's arent like the old ones the dont produce near as much hp as the old ones
@jeepluv76 what does more valves do??? and is it true that 4 deactivation doesnt even matter becuase its still using same amount of fuel? what do they mean by that here?
Awesome engine work on them all the time ,very efficent and easily makes over 400hp with standard factory cam.......listen to all the wankers about 2 valves and its old design .
They should have went OHC with cam phasing timing; better on fuel economy, and even better, more power from most parts of the power bandwidth!
And if they went DOHC with independent cam phasing, even more fuel savings and still a tad bit more power too!

Pretty poor design. Pushrod valve drive and only two valves per cylinder...

Spark plugs are cheap for this car compared to some that specify a ngk laser platinum or Denso iridium.

Yeah the new ones do. They did it for efficiency. The ones from the sixties had a slight problem with this.
