I'll admit right off the bat that I've never driven or ridden in a V10
ram, but I am pretty confident that I can take just about any of 'em, and
I'm far from the fastest Dak on this list. I think I could safely bet the
farm on Tom's 11.5@118 Dak or Dahrl's 10.68@125 being able to outrun a
big ol' dualie. ;-)
While its true that the V10 has a decent amount of horsepower and
gobs of torque, it makes it down REALLY low. Does anyone know the
redline on the truck V10? I think its somewhere in the neighborhood
of 3,000 RPM. Or am I thinking of the Cummins? A motor like that will
tow like a locomotive, but it doesn't stand a chance during drag racing.
Ok, I found some more info; looks like the V10 redline is 4500.
The 1-2 and 3-4 shifts occur at 3500rpm, not exactly an ideal drag
racing setup. (And I don't think its available in a manual. ?)
Check out this actual dyno pull of a modified V10 in a 1995
4x4: http://gn2.getnet.com/~sbelt/images/dyno_peak.gif
At about 2,000 rpm it was making about 470lb-ft of torque, but
it just kept falling from there, and while the HP did slowly creep
up, the curve is rather flat, finally peaking about about 260hp
around 4200rpm.

I've never understood the "how far can you patch out?" folks. :-) Tires
that aren't hooked up don't do anyone except your competitor any good. Its
one
of the basic philosophies of drag racing. You lift, you lose; you spin,
you lose.
:-) That Ram you saw obviously has a lot of torque, but personally, I
prefer to
have the low end a little weak to allow the tires to hook, then start churning
out the real power at midrange and high end where traction isn't such a
big issue.

? I didn't mean to imply that it was any less of an engine, just that
it was better suited to towing than speed. Heck, I love the pushrod engine!
Easy to understand, easy to work on... No DOHC for me, thanks! :-) It just
depends on what you want to do with your truck. I'm admittedly a speed freak,
my main interest is in how fast I can get down the 1/4 mile. So, I'll keep my
V8. (Well, I'll take the 360...) ;-) The V10 just doesn't appear to be well
suited to drag racing.
I've never seen a V10 Ram at the dragstrip, but now you've piqued my
curiosity. Anyone know about what they run in the 1/4? I think the
360 equipped SS/T / Indy Ram's run in the 16's somewhere; seems to me
that subtracting 2 seconds is a fairly tall order for a V8->V10 swap.
