If GM multiplies the 6.0 times 10/8 in displacement AND h.p. that will be a potent combo, especially since they will have to price it near what they are now charging for their 8.1. It would have more cubes AND h.p. than the new Frankfurt/Mexican/Canadian/Mopar SRT-8's and be well past my new 362 h.p. F250.

 

I heard that the 8.1L is going to 380 h.p. and 485 ft.lbs. in 2007.

 

That sounds good! Hopefully they will do away with that godawful slanted eye look. I thought 362 in my new XLT V-10 sounded like a lot but some of them must have escaped somewhere.

 

I know what I am going to say will be disputed, but I comparing the 6.0l Gen IV is hardly comparable to the 265ci Gen I... (especially if you consider going to OHC a big change).
The likes of fuel injection, full alloy block, deep-skirt block casting with six-bolt mains, coil-near-plug ignition system, hydraulic roller lifters, reverse-flow cooling, coutless revisions to head design, availble in about 8 or 9 (I can't remember) different capacities.
About the only thing the same between the 2 engines is the 4.4 bore centers.
The death of the SBC IMHO was with the LT1.

Well technically small manufacturers are still using the Rover V8 in road cars (Westfield etc.). I was talking about the end of production for large scale production vehicles.
The buick aluminium V8 (if memory serves me correctly) was first introduced in 1957, and ran in full scale production cars up until 2005.
Am curious is the SBC being installed in any production vehicle? or is it merely sold as a crate engine?
Do you know production numbers on them? as mentioned I am just curious.
NSU first released the rotary engine in 1964 in the NSU Wankel Spider. Mazda purchased this engine for use in the Cosmo Sport in 1967, and have placed small improvements to the design over the years. Fundamentally it is still the same however. And it is still installed in production cars today.
I suppose you could call OHC a reasonably large change, but apart from that, the block is essentially the same. Still in large scale production today.
First in prodcution cars in 1959, I believe it is still being used in the American Formula Ford, and it was the Ford KA's engine up until last year, in the same configuration as it was in the Anglia in 1959...
Again, curious, when you say "developed", what do you mean?

I am not saying the SBC is not a good engine, it has been a great engine for GM, but there are other engines around the world that have stood the test of time equally as well, if not better.

 

What you said CANNOT be disputed. There is not ONE SINGLE PART shared between the SBC of pre-'97(?) and the current LS1 based V8's.

I didn't know about the bore centers being the same, but on a side note the current 5.7 version uses a smaller bore and uses less head bolts than its predesessor(sp?). Again, absolutely no interchangeability between the two.


The current 8.1 is a direct relative of the OLD 454. The HP has actually been reduced recently..........getting more difficult to meet emissions I'm guessing.

Curious to see a link to the 380 Hp upgrade alluded to earlier in a different post.

 

The specs were posted on a GM forum that I won't link here, and taken from some advanced GM info they were forwarding along to techs. The interesting part was the 6.0 should be putting out more HP than the 8.1 (400's been thrown around), but less torque. I don't expect Ford will be sitting still while this goes on.

 

Yes, that's where I saw them. BTW, the 8.1L, sometimes called the Mark VII, actually has 2 more head bolts than the Mark IV-VI. The heads are quite a bit different than previous Chevy Big Blocks. Most of the high performance 'crate' engines are based on the older design.

 

Is the 6.0l truck motor is essentially the same as the motor in the SSR isn't it?
Except the SSR has an alloy block, and the trucks is cast iron... But still the same figures would be achievable.
Whether it would be a good truck motor though would be interesting. I have driven a 2005 GTO, and the engine is very tractable, but in something that weighs twice as much pulling a 10000lb load, I am not so sure...

BTW, congrats on the 4000th post too!!!

 

Guys! Keep the good news coming!!!! Like mentioned, Ford will probably not stand still while GM brings out the h.p. and torque increases. I LOVE it! I thought the 362 h.p. in my new V-10 would perform but am not yet impressed at all. I have a 7.5 E350 15 passenger van that has 240 h.p. that seems faster, so if more h.p. is coming from the American company I get an employee discount from (thnx to bro-in-law) or the American company I get a GM Card rebate from, I will have some great choices coming. Meanwhile, I AM enjoying the new F250.

 

Yes, the truck 6.0 shares a lot in common with the 5.3, but the cast-iron block is a big tell. The truck motor was designed with an eye towards durability as a higher priority- keeping in mind the trucks are more likely to be abused, often, than the cars.

 

And Trucks weigh a lot more, and weight distribution means a lot less, hence you can get away with having a cast iron block.
Try having a lump of cast iron sitting up the front of a Corvette...

Danko, how many miles on your V10?
Is it fully run in yet?

 

I am over 400 miles now and the ponies are still lost somewhere. I got the 315/70 x 17 BFG's on the rear yesterday (20 more lbs. per tire) and today I got a $130 estimate to replace my muffler with pipe.

 

Sounds like your HP is all in the tires.

 

There sure are not 362 horses under my hood!

 

Wait till you have around 6000miles or so on it....
Believe me.
If you check out the V10 forum, all of the guys said it has taken that long for it to be properly run in.
And once it is, by gee they move...
