We are not due out until Easter now. Darren has offered a 400 block so we will probably use that and just transfer all the internals from your old enginge into the new block. That will put us back to where we were before.
It should be fine, it was still running consistant 9.9's, launching a 5 and shifting at 6500, It looks like there is a crack in the block letting the water into the oil, so it should just be a case of getting the block machined and swapping everything over.
I will be selling the tunnel ram soon if you have a use for it
The production style engine sends oil to the rocker arms through a passage way drilled in number 4 journal of the cam shalft. The cam shalf has a hole that lets oil in every 2 crank turns. This is ok for standed engines but not for high pressure valve springs. The simple way to fix this is fully grove the cam shalf journal so there is always oil on the rockers.Problem is then you have to much oil so a restrictor need to be fitted in the hole to slow down the volume of oil. Plug hole and drill a smaller hole in it.
Problem is what goes up must come down and when this restrictor is fitted there is less oil for the bottom end.

I once saw a big block spin the number 6 and 7 rod bearings even thoe it was showing a constant 70psi of oil pressure. A fail like this is a clue that oil sent up has a affect on the bottom end

Might have Bananarama! all to do with your set up but worth a post me thinks.
That is well and truly mullered...it's definitely a case of start again from Scratch...sorry to see such carnage Jon.
I've only had an engine go to a similar extent and I just wanted to throw the whole lot in the skip and walk away, but like a mad person, started again!
The pump don’t work coz the vandals took the handles.
