For tunnel bored blocks Rollmaster make CS8000 +5 or CS8000+10
Due to my steel centre main fitted I have some options
Hope this helps someone

If you mean line bored main bearings, that is handy to know.

Cheers
michael

It was a pleasure ausmini. I'll miss all you misfits and reprobates

Good to know.
I did up an S block years ago that already had the mains tunnel height up .016" from stock. I decked .016" off the flange and used an Iwis duplex chain, A+ front plate, tensioner and a 9deg offset cam key. The Rollmaster kit would have helped.

Are these sets ex stock or made to order.
The reason I ask is, I enquiried the availability of these thru the NZ agent & they said they were NLA.
Do you have a contact at Rollmaster I can use as reference
Are they only +005 & +010 sizes, nothing smaller
Do they cost more than the std rollmaster set?

Not sure on price.This is the reply I got from Nornda or Romac who make them.
Hi Ian
Our part number is CS8000 +5 or CS8000 +10.

This is very good news. The website shows how to measure the slack in a new standard chain to determine which one you need.

You'd want to pull your finger out and do some work on this car these may be NLA by the time you think about getting this car on the road as well paint engine bay inside the boot petrol tanks etc
