My Pros have 400/325 and the Nitrons 500/400 FYI.

Why is it you can buy budget shock absorbers from local auto factors for "normal cars" ,fit them and have no problems .

That Daz is the question that they can't answer but is unbelievably true.

Did you have them valved for those spring rates or just 'creep up' on them?

The 'whoosh' the valves see due to the force of recoil on strong springs is much greater, but less on compression which can really mess up the valving when drastically out of spec.

They were valved for those springs, especially the Nitrons after careful consideration and discussion.

Stage 4 heads just delivered from Knight Engineering, full refurb.





Also a box of these to fit.



My wife's away working, the weekends free, stereo in the garage, beer in the fridge.............game on

H404.

Mac, I here you may need a pair of these?

There's not much material left on those is there. How wide is the metal between each chamber? Do you have to grind back your gasket to fit?

No,
1.6mm,
Hope not, will check over the weekend when I get to that stage.

I have lots of work to do first.

Strip rockers, adjust JE supporting posts, shim and fit Yellas, (sounds easier then it is), fit heads, exhausts and a plethora of stuff!

Are you going solid lifters ?

I'd like to, (a bit more power and less bleed down on track) but I can't be arsed at this point.

I want a car for all seasons so I am going the softer approach at the mo, (and it's more cost and time for an ickle bit more go).

[phazed]

Hopefully not!

Today's efforts, heads and exhausts on, JE pillars worked on to fit properly, (thanks for the tips Simon, that's what PH is all about) rockers and solid spacers fitted .

Mostly spaced rockers correctly with shims although a tad more to do, (lucky I'm patient as the rockers have taken over half a day).

I've been in the garage since 7am so a shower, Gin & Tonic and a chilli calling, maybe a little more later

Hmm, using spacers made to fit bigger shafts & different rocker arms.....

Wouldn't it have just been easier to have some made the right size for the YT's and standard shafts they use?

The Yellas are an afterthought of last week!

The shafts are standard as are the pillars, just the JE supports added.

Less friction, better individual adjustment and allows the engine to rev a little more.

What we really need is roller lifters to complete the package but as far as I know there are none available off the shelf.

Yes but I spent ages boring them out for your oversize group1/volvo rocker shafts and trimmed to suitable lengths for those! so I know damn well they are different to what you need for standard shafts diameters + the YT spacing on the shaft...

Looks immediately wrong when I even went to the extra effort of cutting index marks to easily identify the middle spacers & each end one! (which shows straight away you have the 2 central ones fitted on the outsides of one bank...)

Change of plans Dave. As said, I need to space them correctly.

I know the Volvo shafts are a little larger diameter. Is there any reason why I can't use the spacers with appropriate shims given the change of direction?
If not, I'll use the springs.

Always happy to take advice.

Each rocker has a separate adjuster although I may need to shim the pedestals to obtain the correct sweep of the rockers.

New rocker boxes just arrived from Ireland.

Deeper then original to clear the roller rockers.

Tomorrow's job as well as a shed full of other things,

A good price to, 270 Euros iirc delivered!
