I STILL don't see a link. Face it, it ain't gonna happen. I tried searching for info and found nothing.
Unfortunately, you're not going to see it either, unless you subscribe to Automotive News or have access to gmdealerworld. It's a done deal though. SUV's out in '06 as '07 models, pickups a year later. the V10 will probably come later with the pickups. The only "if" is the Cadillac V12. Motor's done, but Corp hasn't approved yet. Nothing changes inside GM.
ok men we have a good one going here the gm 8.1 better stay around! i's a bread and butter marine motor check our mercruiser .com its up over 1000 hp,
v10's will be around. some may not like them but they been around for some time. want to drive a nice one try the vw touareg with its v10 diesel twin turbos 310 hp 553 torqe smooth as all tomorow, v12's they to have been around a VERY long time. longer then some of us old farts are old, some of the latest are in some fancey cars from italy, germany and a few others, v16's any one remember the very old caddy , morman,[alloy block ohv]and i think packard just to name a few , old tech is coming back torqe makes a car or truck move more so then hp. a long stroke makes more torqe big bore more hp so someware we will have to find a very happy medium and be happy withit for a while . each to his or her own i'm happy that way
good thread people

please look at www.exhaustsoundclips.com and listen to the ford v10 with a flowmaster40 on it real good. this is a great site for checking the sounds of any engine s exhaust before you by it.
... a long stroke makes more torqe big bore more hp ...
Lets not make any assumptions here. I had always thought this myself but its not true. Its the cam that makes the difference moe than anything.
In Jan of this year Hot Rod did a short and long stroke BBC build up. Everything the same except bore and stroke. Both of these engine are race engines but the theory holds for anything.
467 long stroke (4.310 x 4.0)
469 short stroke (4.50 x 3.69)
Dyno figures:
Long stroke = 610 lb/ft at 7200rpm and 880hp at 7900rpm.
Short stroke = 690 lb/ft at 7000rpm and 900hp at 7900rpm.
When looking at the graph though it appears that the short stroke really made 990hp. Another thing that is suprising is the torque gap actually widens even more at lower RPM's.
I'm sorry there is no link for this but you can look it up at your local library.
It not really stroke length that leads to torque, it's total engine size. That's why Hondas have junk for torque. Less cubic inches to do the work will mean less torque. Like Captchas said, in general, bore size is a good judge of horsepower and stroke is a good indicator of torque. That was from Popular Hot Rodding.
Another reason that OHC engines are more efficient is because not having pushrods allows for a straighter airflow from the intake manifold through the intake runner. There was a really good episode of PHRTV that was dedicated purely to the Ford OHC engines.

i do not want to get into any big one here, i've been a dealership and wrench for uncle sam for over 40 years so i'm just a old fart, vw is what i mostly work on and since 74 their only motors have mostly been ohc small- long in 3,4,5 ,6, 8,10 and 12 cly models. yes the cam makes a major input into the torqe curve but as i have seen in the past so does small bore/long sroke, it's just to me imm we are seeing a return to some old school tech again, from seeing specs for small/ long times a lot of clys to make the realy needed ci's. but now we go and add f.i., a computer to control emissions and engine op's and by tweeking them can get some amazing hp's
i think it's simply who likes what brand and motor style[ohv,ohc,#of clys] for his/ her personal feelings, like me for racing my drag boat has bbc.my wifes drag car is a ford sb i love them both,my new truck just ordered, after driving all the brands of new trucks, i ordered a f250 with a v10 i personally like its feel and the power is there when i want it.and i love my ford trucks.
each to their own here! they are all good when you really sit down and look at it, yes each also has its own faults its owner has to live with

Reason: spelling
I agree with you here MJD. A V-8 is basically two I-4's welded together. A V-12 is two I-6's welded together. Where does that leave the V-10? I'm sure there are some fantastically engineered V-10s, but it will not be naturally balanced very well at all. When you hear I-5 it just doesn't seem right does it? I think of a V-10 in much the same way. I wonder what it would be like if they decided to go with V-12s instead.
Mercedes has had an I5 diesel for years. My brother has one its a '76 and still runs great with over 240,000 miles on it. Runs as smooth as any I6 I've seen.
