thanks Sandaro. i took rocker cover off and checked valves and i've set timing up correctly so i must've got lucky!

Update: turns out when a Holley is over-fueling then some AIR helps ! Sprayed some start ya bastard without any fuel line attached and it fired. re attached fuel line and opened throttle and it jumped back to life!

the last owner was never going to get it running with timing out 180 and both pos and neg at dizzy connected to the neg of the coil! ill run it again and then re-test the compression

thanks everyone for the help!
