Pressed steel ones are 1:27:1, the cooper S forged rockers are 1:22:1 and normal sintered ones are 1:21:1.

Can't remember where i've read it, i'll have to find the artical...

great work i love engines in bits

Pressed steel rockers that i bought. You get slightly more valve lift with these as they're 1:27:1, rather than the 1:21:1 ratio of the normal sintered rockers but a hell of alot cheaper than some 1:3:1 ratio roller rockers!

Who told you they were 1.27?

Identifying pressed steel rockers. Top shows round pad of the small-bore one - 1.23:1 actual ratio. Bottom shows oval pad of big bore version - 1.27:1 actual ratio.

I stand corrected. The vizard bible isn't too clear on this, but does explain that these rockers are very good, and good for 8000 RPM.


SO, good choice I think.

Yup, definatly the best rockers bar higher ratio rollers.

Should be good for a few extra BHP at top revs...

Hmmm not necessarily the best rockers for me, as in theory it puts the power higher up in the rev range. Using a kent 286 this puts the power riiiight at the top of the rev range.


I saw your using the morespeed phase 3 cam, what sort of engine charateristics will this produce?



Ben

[mike.]

To be honest i doubt it'll make that much noticable difference to where the power is, its only a very slight difference over standard rockers.

The phase 3 is somewhere between a 276 and a 286. Power from 2000-7000rpm, but it can still idle nicely at 1000rpm and driveable in traffic etc.

I would of gone for a swiftune SW10 (basically a better version of the 286) but they're cam kits are pretty dam expencive!

[mini_mad69]

Yeah, well this engine was built on the cheap, I mean extreme budget, so a free cam is the best cam I think. Either way your car is looking great, good luck getting it on the road, I hope you hadon't have the problems that Ive had.

Well you can't complain when its free

Thanks, looking to be on the road by the end of july!

More progress, the gearbox is on!

Remembered i needed to cut the cracked bit out of the gearbox, to prevent in snapping off and falling into the sump. Guessworks told me the crack will have been caused by a previous owner overtightening the mount...



Then put the gaskets on with a smear of hylomar, dropped the gearbox on and bolted it down with the uprated bolts i got from the US with the CMS bolts. Only thing is, when i lowered the gearbox on, the oil left in the bottom of it poured all over the fresh hylomared gasket faces, so what sort of seal thats going to create i don't know...



Then lowered the engine off the stand!



w00p!! It looks like an engine!!

I've just got to get a mate round to lift it onto the table, to get it at a decent height to get the transfer case on then the clutch

[mike.]

Well one of my mates came round and we got the engine up onto the table. It swivels about pretty easy on the laminated top too so it makes it loads easier to work on.



So, made up a gasket and bolted on the fuel pump blacking plate, as i've got a facet competition electric pump and filter king regulator to go on:



New high capacity oil pump on:



Transfer casing on now too (glad i labelled the bolts for this since theres 4 different types of bolts that hold it on!)



Might crack on with putting the clutch on tomorrow, but i'll have to wait till the engine back on the floor before i can tighten up the flywheel bolt.

Only thing i noticed before which worries me slightly was that since the engine was upside down, all the oil from inside the engine was dripping down to the rockers/head. But when i got the engine back the right way up and on the table, i noticed that you could see some of the cam lube i'd put in along the edge of the compressed headgasket. Surely if the some of the oil has managed to seep along the gasket like that, its not going to be an air tight seal when the engine running?!

I realized last night as i was going to sleep, that i've bolted that transfer case on - without the gears!!

Good job i've got a spare gasket!

You numpty!
Least you realised your mistake now, rather than later!

[mike.]

Exactly, if i'd of put it in the car, i'd be forever bleeding the clutch haha. I've been out and put the gears in now while its in my mind, so thats sorted now

My father told me about when he did that, he only realised when the car was back on its wheels and wouldn't go!
ha ha, good job you realised now.

Come one, get it in the car!
