This comes from NoMAD, who posted it in Garry's build of the mild EK.
Enjoy
All that work for 116hp! What was the quoted standard figure?

i think they had about 75 BHP standard, so its about a 60% power incease, which aint that bad.

That article said they used standard Holden V8 valve springs, has anyone else used these and which V8 , 253 / 308 they might well be the same but I've never had one apart to know the difference.

Been told they are all the same as a red 6 as-well, just sounds impressive to say V8 springs

I did a lot of similar things to my motor, I used 350 chev valve springs that have around 85lb pressure. My car makes 105 rwhp with twin stromburgs

Could you list the mods you performed upon your grey Hysteria? I would be very interested in reading them.

without trying to sound like a wanker, that is very low power for the specs. that should do 150-160hp easy. combo is not right at all.

yours actually makes more power. yours would be around 145hp@ the flywheel, so it shows how poor the engine in the story really is.

O.K. I can't remember where I read it but I think it was something to do with a old speedway magazine but they mentioned putting a Falcon 6 crank in one? that enabled it to be stroked? don't quote me

I've heard of the falcon crank into the red 6 for stroking, not in the grey
