Ok, update!

First off i relocated the fuel pump next to the fuel tank under the floor.
Then i checked cam and ignition timing. I found that the advance weights on the E15 dizzy were sticking and 1 of the springs wasnt doing anything. so i raided a spring off a old a series dizzy and lubed it up and it works beautifully.
But it still wouldnt start! Thats right it wont even start now! I have fuel and i have spark. But it seemed a very weak spark. So i made up a A series points dizzy (new cap/rotor/points/condenser) and it seemed to beef the spark up. It tried to start once but chugged and died. Now it wont even try to start/backfire... NOTHING! Then i ran out of battery so thats why im here typing my findings.

I had it idling away for ages yesterday and free revving well, but as soon as i decided to drive it, it packed the ####s and yeh now wont even start!

And theres no oil in water/water in oil incase your thinking head gasket
