- Steve's setting the initial lash on the valves
I'm going to test fit the intake.
This thing is going to be sweet.
And, it fits perfectly,
but we want to run a vacuum pump on this thing
instead of running a bead of silicone,
we're going to have to figure out some cork.
What Steve's working on right now
is what's called a stud girdle.
So it uses a really long poly lock,
which is the thing that holds the rocker arm down,
and it is a clamp that goes around
each one of those poly locks to stabilize
all of these rocker studs so that they're not
wobbling around with the high spring pressure and big lift,
and potentially rpm of a solid roller cam.
This thing doesn't really have an rpm problem, fortunately,
but this is still going to add valve train stability,
since we don't have a shaft mounted rocker.
It's a regular old stud rocker.
This is the same rocker we took off that other engine
on the stock heads.
- [Man] This just goes in.
(metal clanking)
Okay.
- [Steve] How big is your dominator?
- 1250.
- Oh, good.
- Yeah.
- [Steve] Why'd you put the small one on?
(David laughs)
They make a 1420.
- I asked you, you wanted this one.
- [Steve] Yeah.
- Well the old one was the Freiburger combo,
this is the Brule combo.
- I like the Brule combo way better.
- Probably.
Yeah, we got the whole Brodix setup dialed.
Steve Brule is now going to tune this thing up while
we go hide in a corner,
and then we'll come back and find out
how much power this thing makes.
Alright, I think you guys are about to be
a lot happier with this engine.
- It's a little more what I'm normally doing.
- [David] I know.
- I suspect I'll like it a lot better, too.
- This things going to be stout, watch this.
- You're the odd man out Freiburger.
- I know.
(tense music)
(engine revving)
That's more stout than I expected, by quite a bit.
I didn't think 10:1 compression ration would get us there.
So essentially, we just bolted on 300 horsepower.
- That would be a cover blurb.
- I know!
Not even essentially, we did just bolt on 300 horsepower.
- [Steve] Almost, actually a little better than three.
- So this thing just made 774.9 pound vita torque,
and up top: 853 horsepower at 6,300 rpm.
Now what blows my mind, actually,
is how much more torque it made than the small combo.
It just bumped it up, but look how flat it is!
What's it making down here, at 4,500?
- About 774 (laughs).
- Yeah! 762.
So a lot of people will look at that, I think,
who are not familiar with these types of things and go
oh well this made more torque,
so this is more the torque engine,
but the whole key is the rpm range at which it happens.
- Even down at 3,600 it still made 673 so it is a beast.
- So that's the overlay. - Oh wow.
- Of the iron heads versus the Brodix top end combo.
These red lines down here are what we did with the tiny
camshaft and stock heads,
and look at that.
That is what's going on.
This is a real visual that tells you that even
though this is making way more torque,
I think what people think of a torque motor
they're thinking of torque that is easily drivable
at low rpm at part throttle position.
- Torque at low range and speeds,
not at max output of torque.
- I know you guys think I was cracked
walking into this test,
but what my goals were for it were first,
to find out what happens if you basically put
454 parts on a 598 and second,
to talk about the difference in a torque motor
and a horsepower motor,
and it backfired on me a little bit
that the horsepower motor also made more torque,
but what are your takeaways from this?
I mean, there's more engine dynamics going on here
than we've really talked about,
what has it made you think about?
