has anyone made a 3000?

[no_doz]

while tinkering around with a displacement calculator i found out that a 3400 with a 2.8 crank ends up at 3.0 (eat your heart out ford/japper's), short stroke & big bore-has anyone made one of these?

just as a thought, with a good set of rods, pistons, valve springs, & a cam for it-wouldnt this be one hell of a high rpm 60* pushrod monster? also would the crank work or would it require some sort modification/alteration?

I know Ben had talked about and we were seriously thinking of doing this to a DOHC, lol. Now THAT would have been a high rpm screamer.

[no_doz]

YIKES-is the crank of any concern as far as high rpms are concerned?

just stop for a minute, close your eyes, and imagine the sound of built & destroked 3.0 LQ1-hitting 10,000 rpms with a good tune & cam profiles for it

[pocket-rocket]

Ben was talking about using the forged crank from the j-body store.

[no_doz]

nice! ill put money on a built & tuned 3.0 LQ1 on ruling the streets-ricers & honda/acura lovers will be whipped into a frenzy of tears & cheap ebay turbo kits, resulting in many blown engines and an overall change in the balance on power on the streets.

its the revolution

"Has anyone made a 3000?"

Umm yea, 3.0 Spinned insane RPMs, Put in some lame FWD box on wheels, Loves boost











Reinventing the wheel guys hint hint Yamaha, cough cough s-h-o

I think the question was, has anyone taken a GM 60* platform and made a 3000 motor... Not has ANYONE made a 3000.... since um yeah this is a chevy 60* orientated forum, why would we care about "hint hint yamaha, cough cough S-H-O"

Didn't the Buicks in China have a 3000?

if this is what you're talking about its nothing like the 3000 that im asking about-but DAMN

I6 24 valve 3.0L

3.74" bore & 2.748" stroke

-thats one hell of a big bore short 24v GM motor!!

[IsaacHayes]

Yes the Chinese have:
2500 LB8 which is a destroked big-port 3100 LG8. 145hp/155tq.
3000 LW9 which is destroked not as much and is 170hp/185tq.

I bet that 2500 gets good MPG. Those engines are neat, but what I think would be cool is a big bore destroked motor. That is take a 3400 with 3500 top end, 2.8 crank and high compression and a cam. That would be about 3.0xL and have a hell of a lot more power than the chinese 3000 which is just a destroked 2000+ 3100....

that is EXACTLY what im talking about


also-if someone were to make one of these & get rods & springs to accommodate for the rpms, is there a currently existing 3x00 cam profile that would allow such an engine to produce steady power to 8000 rpms?

[IsaacHayes]

Well that setup is just what my new motor is except mine keeps the stroke and extra displacement. Less MPG but more power.

A custom cam could be made, no real limit now on the gen3 cams... Another problem though you might run into is finding a trans that will shift at that RPM. The 282 is not rated at that high of input speed. Some find it hard shifting a lot less than that anyway.

[AaronGTR]

That was my thought. I doubt you'd get 10,000rpm out of it. Maybe 8k, maybe a little more, but problem is not getting rpm but being able to shift that high. GM doesn't have any transmissions designed for these engines that will shift that high.

[no_doz]

what about the F40-couldnt that hold up to 8k?

[AaronGTR]

Don't know. I looked but couldn't find anything in GM's documentation about maximum shift speed. All I found was that they changed the gear ratios between 2006 (MT2 F40) and 2007 (MU9 F40) to have higher ratios for 3rd-6th gear for faster acceleration, and that it's rated to a max of 295ft/lbs torque and 3527lbs vehicle weight.
