Vulcan roller rockers

27 posts in this topic

So, as it's me, and I'm never content with anything I do, it's time to attempt to add moar power to the vulcan't. Or die trying.

I had the opportunity to buy two sets of rockers from the late "rudedog" from Tcca. These are crane 1.7 rockers with studs and guide plates.

To avoid the headaches of morana and machining pedestal mount ones, this is the route I always wanted to take.

These pictures are from a quick test fit I did today after saying "there ain't no way in hell this is gonna work" and it might work.

I have to tap new threads into the head as these studs are an SAE thread and the vulcan is metric. 22c49e396107570a7209c019c2e26f87.jpgce74a9021bdb663e3afb6df8acd9db02.jpg2fa16cb0a6a17ac29aa0fa07e6c4f325.jpgc9fc7b81e1a0ac860cc7610aa2b7ad06.jpg

I'll update this as we go.

Literally ZERO confidence from the peanut gallery. Don't worry, there will be plenty of bent pushrods to go around!

Just remember this one thing from my experience trying to install roller rocker arms on a Vulcan... $938. Know that there are at least 938 good reasons to take your time and assemble those heads properly.

You can get a complete long block at the junkyard for like $300. And I'm not worried, pushrod engines are pretty hard to fuck up

After much bumblefuckery around on the OTHER site, I believe these to be the "Fredness" kit. The dude who ran stuffforyourranger and rogueperformance websites for the rangers.

Most of the info is over 10 years old, and all of the links are broken and all of the pictures are missing.

Sounds like a lot of the old builds on CVN. Go to see something that sounds cool and the page is rendered generally useless. Just going based on the text only gets you so far. I feel your pain there.

They're either reliable or bitchy. Hopefully it'll act nicely once you're done.

I don't even know if its about the gains anymore. I don't think there's actually any to be had with the boat motor of a vulcan. But I couldn't let these parts go away, they were gonna get tossed in the bin if I didn't pick them up.
The one set is brand new and never even been run. 
And if this doesn't work, im sure they will be fine collecting dust on my shelf until a 351W or a 302 rolls into my life as im sure it will eventually. They are the same parts after all

You do need a 5.0 Fox.

Having rode in Rudy's car, I can attest that his Vulcan had the ever allusive "moar powah". Rudy was a very large man and his Gen 2 Vulcan would keep pace with my tuned '99 SE Duratec.

Buy it and I'll gladly take any spare components that you remove from it that you don't need. :)

It would not be hard to get power out of that 302 with a few upgrades and the rest of the drivetrain is archaically simple.

I say do it! My Roadmaster is pretty damn quick with the LT1 with a shitty OptiSpark... Can only Imagine a Country Squire with an LS V8 :wub:

You've got good timing@jaybrooks I just did the install on these over my long weekend. And a handful of other back maintenance.

Wow that's looks great how many hour did that take for you to get this done because I want to do this for my Vulcan ... vulcans are misunderstood sleepers and durable

^fixed that for you

Leave yourself a day, a good 6 hour block of time. It shouldn't take that long but take your time.
If you've never done engine work I wouldn't recommend it, This style of rocker requires manual lifter preload and its very easy to make them too tight and damage the lifters.
In addition you have to re-tap the head and shavings in the oil are never good.

I will say that it frees up the top end alot, you get some more useable RPM above 4800 which is nice, but it doesn't make it into a "performance" anything and hardly a sleeper

4800 rpm is really good on a Taurus Vulcan did you take out the rev limiter?

Stock rev limiter on a gen 4.5 is 5800 rpm. The vulcan heads don't flow very well up that high though
