....build my engine?...Getting to a stage now that i have spent so much money DIY could spell disaster

..As we all know it aint rocket science assembling but if something goes wrong with installation i can blame Mark
Please be aware he would be building it to my spec

..and will not be responsible if something fails unless its a build issue.
I am fully aware that in essence it will be a MAD engine BUT not a MAD spec although he said it would be good to test my method out
The only problem with me doin this is the issue of a DIY record....whats the most importane aspect of a build...the actual build or the specification???..If its the latter then its full DIY...I will read with interest the usual mixture of mainly crap reaction with the very odd sensible reply.
