ok so here we go guys i have sorted the problem i think
i ended up putting on a 180 holley and then it just drove fine it doesnt starve on fuel anymore well this is my test from driving it but i am yet to stick it back on the dyno to find out for sure
however i did notice when modifying my airbox to accomodate the holleyi found that the meta had cracked and split just on random bits of flat surface so i repaired these cracks modified the box and it drove fine but seemed to have less power then the weber so installed a bov i thought that then it would b able to release the preassure wen needed to hopefully not split my airbox again...

now the only drama is that it runns real hot and i am not running an intercooler if i run one would this help? or should i get a new radiator to help with this????

any help apreciated thanx andy
