Well you drive something with a 3800 so I'm going to assume you're a Grandpa and drive 20 under the limit all the time.

>>16885301
That's not how you conserve gas. You ride smooth using your torque wisely to high speed, then coast, revving to nurse the driveshaft. Sometimes I cruise control, but mostly I like to drift between 5 mph then open it up when it's safe.

Probably obvious but do Big Blocks not meet emissions? only reason i can see not putting one in a Super car. you'd think GM would've put it in a mid-engine vette by now or at least when it could meet emissions out the factory.

Technicly you could meet emissions when you get a EFI and catalytic converters for it.

The port sieze of a 3;4 or even 5 Valve cylinder head are, when combined, even bigger.

>>16885470

Yet they make less power than the "ancient" 16 valve V8... Really makes you think...

>>16885469
240Ps os much for a engine that small.
>>16885475
If corrected for displacement, these 32 Valve engines make much more power than a 16 Valve V-8.

>>16885467
Indeed, the rev. limiter is set too low, it can take 10.000rpm ad get a decent powerband when the rev limiter is set like that.

>>16885484

A NA 'Busa engine makes that much while being lighter

What's the point of comparing displacement if the higher displacement engine is physical smaller? Why would you even use a dohc boat anchor?

>>16885514
They can take these revs, and Takumi revs his 4A-GE even higer at 11.000 and later 12.000rpm before he destroys it at 13.000rpm.
>>16885515
A DOHC engine usually isn´t that much bigger, especialy on inline engines there is pretty much no difference.
Also e DOHC engine needs much less fuel than a OHV of the same power.

Probably the flathead v8. Horsepower is not the greatest but they will run forever and can be rebuilt and repaired easily and cheaply.

The coyote 5.0 is also a very good engine because of how tunable it is and how much potential is still available with the stock parts. 1.39 hp per cubic inch and 1.32 lb ft of torque per cubic inch while meeting emissions standards on pump gas on a production naturally aspirated engine that will run 500k miles is impressive

Spark EV was the best kind of beta test. Shame it's gone now, was literally the best hot hatch on the market.

Still less raw flow than a good 2v head, which is all you need for power.

Also, you can still make good 4v pushrod heads that'll go up to 9500 RPM.

>>16885484
Yet those engines are a lot bigger for their displacement.

Pushrod and DOHC make about the same power for their external displacement.

>>16885532
>A DOHC engine usually isn´t that much bigger, especialy on inline engines there is pretty much no difference.
On mobile right now, can anybody show this guy the difference between a 5.0 Windsor and a 5.0 Mod motor? Fyi, you can fit a big block Ford into a late first gen Mustang. Putting a DOHC Modular in that very same engine bay is a pain in the ass. Packaging DOHC V motors is a lot worse than their pushrod equivalent. You're right about inline engines, but those are worse than V's in weight distribution when they're more than 4 cilinders long.

Actually, pushrod engines can get much better MPG because of the easy implementation of VVT, variable displacement and direct injection.

>>16885722
The Voodoo is actually incredibly pathetic when you compare it to any other modern flat plane V8.

>>16886437

2v heads don't have better flow for a given bore size, there just aren't any DOHC 4v heads made that have bore sizes larger than 4 inches, and all of those are factory castings which have to meet be both economical and have good low lift flow compared to aftermarket castings targeting the performance/race market.

why, that would be the Mercedes-Benz OM617
