Pre X-Rocker arms

[TCSTEVE]

Guys i kjnow this may seem like a stupid question, are the yella terra roller roccas for the pre Xflow head any different for a 2V? And is there a cheap alternative like the Clevo V8 stuff is for the X flows?
Need help Cheers Steve

Nope - same part

And is there a cheap alternative like the Clevo Vee-Eight stuff is for the X flows?

Nope - specific part I think
Yella Terra do a "Street Terra" range of rockers that are reasonably priced.

Y/T get the T-nuck award for what they did with the rockers about three years ago.

They dropped the Yella terra forged/extruded ones for this motor, and kept producing the Street Terras, which are vacuum die-cast and carry much less warranty. They also popped the price up closer to the old Yella Terra figure.

I called around chasing old stock - no such joy...

My next build will be an OHC. Better initial platform.

Cheers Tuffzc/addo, ive been informed that there was a difference between the log and 2V :roll:
But come on guys theres got to be some trick part that can be borrowed off another motor. I want a 1.6 rocker ratio. For the price of those street terras i could buy two cams, one with really high lift or one good custom grind
Cheers Steve

Or two EL drivelines that had roller as standard... Now you see where I'm at.

how much for a set of EL Lifters?

I've not priced any parts of the OHC motors as yet.

But I get narked by business decisions such as that with the rockers, diminishing availability (read pricepoints) of 221 and 2V stuff, comparative cheapness of the OHC cars and marginalising of the whole "car as an active hobby" scene. People are so hocked up, mid-grade modifications are really dying out. It's either a dangerous piece of junk, or a mortgage-worth of paint and billet. I've no interest in associating with either group.

I'll never own another V8 unless it's a resale decision on a new car. And I like the quirky swaps as well - a Hudson or Chrysler flat six install would be cool but practicality leads me back to the Ford engines.

You might be alarmed

How about a 2.8l turbo Isuzu diesel?

Oh hmmmmmm, singing from the same hym book, brother!

The Americans have a market (Just under 16 million new cars were sold in the US in 2004, verses 980,000 in Australia the last 12 months.

Since the market is 1/16 th, or 6.25% of the American market, its all due to economies of scale.

Soon, we'll be importing parts from FSPP to make up the shortfall.

You stick with the OHC's, but you'll find the real budget winners will be us with old, old OHV engines will have more aftermarket support becasue the cost of electronic control, emission compliance, and transmission rebuilds havel killed the aftermarket for 7 year old cars.

Im sticking with the 2V for my drag motor since ive spent too much on it already, just goona get a high lift monster cam since i cant get 1.6 rovkers. I dont give a shit about driveability and cops.
My idea of cheap is a ginder a dremel and a log wish me luck
cheers Steve

I never said don't buy the rockers. But what YT did, should not go unmentioned or censored. They buried the change, which I dislike.

Yet I would still pick up their roller rockers before buying any other brand. Also, before installing a high lift cam, I'd go roller. Engine life and frictional loss improvements make it sensible.

Hope you were joking about the Isuzu motor, Mr ZC. Other interesting donks would be the AH six - all alloy version by CHI, the 265 and 225 Val units, blown Offy four, a retro-build flattie with Riley or Navarro gear, XJ six, maybe even a Merc diesel if they are tweakable...

Nope - I'm looking for a diesel engine that will go nicely into an XY engine bay for our Bio-Diesel future...

 

[aussie7mains]

Are we confused here?
The precrossflows have shaft mounted cast steel rocker arms with adjustments, thats ALL of them in aussie anyway.
I dont know of any repalcement for then and rollers wouldnt be neccesary anyway.
The crossflow has the cleveland style non adjustable which lends itself to any of tyhe cleveland thingies including stud mount rollers.
the OHC has roller hydraulis with two types 1.8:1 in early and 2:1 in later engines with 'reduced inertia" arms and cams, the two cant be redily interchanged as the cams base circle, roller, and stands are different.
You shouldnt need any work on them as theyre good as is.
I wouldnt be trying to lift the valves any higher than about 14mm max, which is probably higher than optimen with the valves sizes anyway.

Good old bio-diesel. If it were legal to grow hemp, we'd have a great oil source there, plus a healthy textile industry and enhanced soil quality.

 

[xctasy]

And every 'reafer' would come with a miniture catalytic converter, made with real South African Rhodidium and platinum...

Hemp is a good crop. If someone's silly enough to get permanently stoned off it, that's their biz; once we work out RBT for pot that'll be sorted. There are other good seed oil crops but they tend not to have as versatile fibre products.

At the risk of returning to topic , I still stand by fitment of rollers to these early motors. It cannot make them worse.
