As I learnt, if it is someone that knows what they’re doing, it also depends on whose steel caps you’re intending to use. Some need more passes than others and hence cost more

If a Yorkshireman went all the way to Suffolk, it must be cheap

Does the machine shop know what size the caps are supplied at?
Swiftune ones are a lot closer to finished size than MED.
Gosnays in Romford charged nearly double to do MED caps, normal price was £185 to do Swifty ones.
The money saved buying the cheaper MED caps was false economy...lesson learnt.

If your having a block line bored with steel caps you want somebody that will do it correctly and in tolerance , not looking for the cheapest job .

Thanks for advice, not looking for cheapest over quality, but its not something I have done every day, trying to get a feel for how much prices and quality varied and maybe some recommendations

This, £260 is well spent if the job has been completed perfectly.
There is also a massive difference between line boring a block with new caps to whistling through aN existing block with a line honer.

Norman, hope you are keeping well? Without any doubt 25 Eng and Elgin Greer have my vote 100%. The cost above was a mates rate.

Scholar dont work cheap but do give value for money. I have dealt with them for 30 years and Alan Wardropper is a friend but that's not why I use them. I find there work consistently of a high standard, when an engine arrives its properly finished off. I am especially pleased with the restoration of my 1970 andy barton S engine which they did. They were/are best known for Kent Formula ford building so know engine machining backwards. But they do all makes and actually have quite a depth of experience with a series and did my fia mini heads part cnc finishing by hand and flow tested against competitors. I am sure there are plenty of other good engine shops about and normally its a personal choice.

Classic example of a bloke copying something without measuring or examining properly
