Woahh you clearly have got some free time to write my dear.
Good informative thread.
But then again...i will stick to what i said...for reasons u will.not understand. 
Overhauling an engine is different...a complete restoration is another thing...it affects the car value and other aspects...so discussing the costs is not a idea...if u someday want to sell any of that stuff or the car itself.
Ure obviousky not going to part out or sell ure engine. So i hope now u get it.
A person does all the hard work for 4 months...find a part for lets say 5k after visiting numerous places for 3 months...consuming time and money and petrol. And posts i bought it 5k after a bargain. Now in future if hes upgrading...and posts the same thing for 7k...which is very very decent and i dont think by any means could be categorized as profiteering. But still ppl wont get it...they will most definately be like u got it for 5k and are ripping us off. Chahe market main 8k ki ho wo cheez.
Now u get it?
Same goes for the car...nobody give a **** for the time money and sweat u put into something...they will need hard on figures of everything and they will put a price tag on ure car...neglecting the fact that this guy got his *** blasted and hamered for 6 months to put this thing together with something more valueable than money.
So thats why it not a hardcore rule as u might have thought i m inclined to dictate but a mere sensible food for thought not to disclose prices publicly...but yes always be helping enough to accomodate almost all the price check requests privately.
Ab Allah k bandey....dont think i m being offensive..we are here to guide each other with supporting arguements. I have given enough i think...its upto u to live the way u want anf i have nothing against u or am not trying to prove anyrhing...just given my point of view to which almost everyone would agree.
