Roller Rocker for a "Mild" Street Stroked 427?

[Drew Pojedinec]

This is one of the reason I used factory adjustables.  Very simple durable setup.
With a street cam, the sliding surface isn't really all that much slidin.

Yeah, there are a couple of companies now offering complete setups with new rockers, shafts, springs, etc.   It's a great offering.

Sorry double post.

Brent,
Can you post or PM the companies? My search is coming up empty.

They are usually available through engine parts warehouses.   You can have your builder check for them.  I buy mine through Motorstate.

Quite a savings over T&Ds that's for sure!

Where is the break point as in lift, spring pressure and such between a set up like that and rollers.

[blykins]

I've ran them to 6500 with about .600" lift and 350 over the nose.

[ACHiPo]

Finally got around to contacting T&D.  They recommend their steel rockers for street use--an extra $500.

My opinion is .600 lift is about as far as you want to go due to side loading the guide as it paddles across the valve tip.  A good radius on the tip, and dialing in the stand height is important.  I won't use the OE rocker past 425 open pressure.  Seat pressure is really no issue.  I have been working on camshafts that have .525 lift, and valve jobs that maximize flow to .500 lift,  to go along as a package for long-running street use with the non-adj rockers.   High lifts on the street will wear things out, and planning around a lower lift program can still make big street power and maintain long term reliability.

We get the 427 Stock Eliminator cars in the 9's with .500 at the valve, and 390s in the 10.30s with .481/.490 lift.  If one approaches it right, longevity on the street and low lift power can happen.

So I seen the "an extra $500".
Well I must look that up.
I go to the T&D Machine Products site. Love that spiderweb.
They are not giving up the price there, but they do give out tech.
It say's that the stock type are 1.60 and the Blue Thunder Thor, 1-piece Stand    
1.650.
Is this true?
I have never measured a T&D rocker.
That's giving up a lot of cam if it is the case.
Most are measured at least 1.73 stock.

 Unless you lack confidence in your engine builder, I would let them make the call on the rocker arms. They may or may not be in agreement with what you decide. With that being said, if you knew how many hundreds of FEs are out there running on the street with T&D aluminum street Rockers, you wouldn't be second-guessing the durability.  They have good parts.

Man I have been running aftermarket alum rockers for a LONG time, in fact, my current set in the 489 are over 10 years old.  I have seen some Comp and Dove's break, but usually only with high spring pressure, and keep in mind those aren't bushed or bearings.  My Ersons I think will last forever at flat tappet pressures, the weight is distributed across the bearing case and the pressures on each end just aren't that wild on a pure street engine

That being said, with hydraulic roller I am a huge proponent of the stock hyd rockers. However, I wouldn't hesitate to use any available name-brand rocker out there, and Ersons or T&D streets I wouldn't even think twice based on a failure rate of zero on every set I have seen or used.

I also second Brent's comment and add that if you don't trust the guy to pick a rocker, I am not sure I would trust him to build it....

[CaptCobrajet]

I think the T&D is the best aftermarket rocker there is for the FE, in most cases.  It does cost more, and there are builds that just don't require them.  I don't think the aluminum will give up.  I ran a set of Scorpion aluminum rockers over 100,000 miles in a 514 cube 385 series engine in one of my trucks.  I sent them back to be checked out, and they just sent a new set.....said they were lifetime warranty.  Point being, the aluminum body did not fail over many miles with hydraulic roller spring pressure.  I just like the simplicity of the non-adj rockers in engines that can use them.  A little less money, and less moving parts.  If you desire a roller tip, the T&D is the best, in my opinion.  If you ran a solid roller in a cigarette boat, the stainless with paired shafts should be used.......
