what's the difference between that and a standard crank Phil?

This crank is fully counterweighted with 8 counterweights. The std crank although strong is only partially counterweighted with 4 counterweights

Is the new crank still lighter than a standard one? just wondering.

You could get it knife edged and nitrated, while your going the hole hog.

My old man had a look here on Xmas day.
He was impressed with the new paint, cage and hood lining colour.

Hello, looking really neat. Question, those solid followers you got, are they from Kent or someone else, and if you don't mind, how much where they. I've had a look but it seems around 600 beans is as cheap as I can find for a set for mine??

Hi Mark,

I probably wont worry about knife edging the crank as Im running a windage tray but will see what my engine guy recommends when he sees the crank. Hopefully I can catch you and your dad at the next Nostalgia Drags at WSID if you guys come down, the car should be running by then...hopefully

Hi Chris,

$600 is about right. I got my lifters out of Arrow Precision, I wouldn't be suprised if they are the original manufacturer for cam suppliers in the UK. You will need to know your final head spec before ordering as they come in different stud heights for differrent length valves.

Cheers,

Phil.

Thanks for that Phil, I assume the specs they require are valve length and cam base circle. My cams have 2 different base circles, the exhaust is 2mm bigger than the inlet, do the shims that come with the followers come in a wide varity of thicknesses, or is that mm taken up by the stem spec?

Hi Chris,

It all depends on the clearance between the valve tip and the cam lobe base circle as to which stem length you would order. The shims are sold seperately, I haven't purchased those yet as I haven't decided which valve stem diameter I will be using. If one base circle is smaller than the other you can bet that cam is a regrind rather than an original.

Cheers,

Phil.

Both the cams are mountune grinds, there just very different in figures, inlet's 12.25mm lift and exhaust is 9.2mm lift. They are a matching set. Due to the lift on the inlet, the base circle has been ground smaller so the lobe still clears the material around the follower. cool, so basically you order followers for standard valves, then measure for shims, thanks again for your info.

No worries Chris, I bought the 17mm stud option for mine, I will be running close to std length valves. How close are both your cams to 37mm base circle?

Phil I'm surprised they have cross drilled the journals or fitted plugs to the B/E lightening holes to act as a crap trap As far as knife edging it isn't as widely done anymore as it can create dramas with end thrust is not spot on and there doesn't seem to be the big chase to get the weight off as it's spinning in such a tight circumpherance as I know my cranks are a touch heavier than yours and it has no problems accelerating the weight as it's still repsonsive enough to pick the alternator brushes up and punch them out the back
What material did they use hopefully not some EN40 crap

PS Mark it has been nitrided just have a look at the satin grey finish on all the non ground surfaces
