Re: NOJIMMY(Larry's) Typhoon coming back to life!
Those are not your typical stamped steel rockers. They are the GM roller pedistal rockers similar to the LS rockers. I ran them on my AWD Ty well into the 10s. When I had my heads done at Flowtech they recommended these over the aftermarket rockers. They also open the valve sooner adding a touch more duration because of the longer rocker/stem contact than a roller nose after market rocker. I was convinced by the company that helped GM design them that a 1.5 ratio in these will out perform a 1.6 after market because of the design of the contact nose.
They put less weight on the valve train because they sit on a pedistal bar instead of sitting on the valve and spring assembly in the stud style application. Once adjusted correctly with the right push rod they don't have to be adjusted again even if you take the head off and replace it (provided you use the same thickness gasket).
Hands down the best valve setup for vortecs.

We're crossing are fingers in hopes that the motor and trans are going to work!:tup:
The valve covers were pulled off to make sure things were tight and discovered it had stock stamp steel rockers instead of the Jesel's that he paid for.....bummer!:tdown:
Drop down this week if you get a chance.

Re: NOJIMMY(Larry's) Typhoon coming back to life!
You are correct about the motor being fine with them though since it will never see much more then 6500rpm and they won't require much maintenance......not to mention the low cost over a Jesel or T&D style setup.
I do like the fact they are tied together at the pedastals. It hasn't run yet though so can't give a report. 'Top Shelf' stuff like, Jesel/T&D, on LS's free's up HP, so I'm sure they are worth the money, as per usual.
I like steel in almost anything.... you can't really tell what the duty cycle of the aluminum is because the dynamic forces vary depending on everything, RPM, pushrods, springs, lobes..... but with steel pieces you don't have to worry about it.....very streetable!

Yeah...but when your told you payed for Je$el$ you should get them not factory style stamp steel rockers on a bar, that was more my point. The Jesels would of came with a rocker bar aswell, but a lot lighter and the roller tips will pick up power over any non roller tip rocker.Those are not your typical stamped steel rockers.

Re: NOJIMMY(Larry's) Typhoon coming back to life!
I would not stick up for Guy with this, but I have heard many talk about these style of rockers as "shaft style like the way the Jesels are setup"… with the meaning that they are a shaft/pedestal style type rocker not in the meaning of high performance use. I would not think putting a Jesel/T&D setup on a non offset valved vortec head for our low rpm use would be prudent. If Larry paid Guy for them then that's what he should have received, for sure.
On the power front with regards to the roller tip, I agree on higher rpm setups there is a friction differential for increased hp. What the GM rocker designers told me regarding a roller tip vs these is the "radius" or contact area of this stamped rocker tip is much larger and opens the valve longer and farther at the same ratio as a roller tip. I like you’re thinking as well regarding maintenance and longevity of these rockers, especially on a lower rpm application.
I am crossing my fingers that Stokes truly put this motor together and not someone else…

Re: NOJIMMY(Larry's) Typhoon coming back to life!
I would like to thank many who have offered assistance and comments.
Being a rather private individual, I rarely comment online anymore and avoid conflict
like the plague. Plus I still dont know if there is "light at the end of the tunnel".
I can answer VinnieTy's question,
and its a very good question....10 years...why?
1. Rockford was doing well, growing, moving into a larger shop,
getting high dollar customers (Tim Allen, etc).
Each change in personel, location, customers in queue
caused delay.
2. Part were being custom"developed" through prototyping
on other vehicles/customers. To make a part for me, the
first customer/part had to be tested and the second one built..
3. Large vendors were soliciting sponsorship (like autometer)
which caused the shop to travel and attend other events.
Sometimes getting direct contact was not always simple/easy.
4. I did not have the lump sum money to send to spend
months x shop rate + parts for the desired build. Granted,
some items like the 12 bolt moser was (now seen as)
overkill but sending thousands to get only a housing
(with parts backlogged, or needing more research) was convincing.
5. Not a large population of members have a running
bowtie, even-fire, large turbo, "e" tranny, custom ecm
wilwood braked, Typhoon that passes emissions
and runs daily (to copy from). Thus the uniqueness
with a vision of what it was suppose to look like, drive like
was is a bit unusual (ie show, go, and street).
6. And lastly, I trusted the owner/shop, sent x-mas gifts,
invited out to dinner, and called frequently (plus long
distance traveled) to communicate, not knowing the
outcome. The last two years I was in bad health.
...so, its easy to see in hindsight, not so obvious when
its happening . And while I take responsibilty for my stupidity,
some of the mods first tried were tossed as technology changed.
Blade of death, spal fans, chips, turbos, air foil, atr folding....are examples
Maybe others can learn from my mistakes. Sometimes shows like
Overhauling, or whatever, makes it seem an average-joe can have
a custom vehicle in one week and virtually low cost. Ask John
Gerber (or many others) the money, time and sorrow caused
by having parts vendors misrepresent themselves.

Re: NOJIMMY(Larry's) Typhoon coming back to life!
Larry,
Whats that saying again?
The great thing is the community as a whole is here to help everybody out. In fact being such a tight group has what some would call drawbacks also. Just like when your brother growing up gets beat up in school, you take care of business and ask questions 2nd. It happens here also. Sometimes we are right, other times no so.
But in the end your still our "brother" and I know as a community any of us will do what we can to help you get that truck build just the way you want and deserve.
Good luck.

Just for some reference photographs here's some straight from the donkey's mouth on the initial build on the stock block.

I was hoping there would be pictures of the rocker arms from way back to verify what was used on the stokes heads.

Cool......I think after the new a2a is completed today the only thing left is for UPS to drop off the BS3 and tune it!:tup:

Re: NOJIMMY(Larry's) Typhoon coming back to life!
A little syty porno from Larry's truck! a2a complete,new FP regulator/fuel system done,hydroboost done,distributor in and timed, wires/plugs in.......Cal Trac springs in and lowered with custom made blocks to center the rear wheels, Wilwood calipers and rotors for the new rear brake set up.
Waiting on the BS3 is about it now......can't wait to see Larry's face when it fires up!!
