What is wrong with this combo

I have been told to put a 1050 dominator on it by at lease 3 different racers at the track. One had a spare in his trailer but could not find the manifold adapter.As far as the cam goes he was trying to build cylinder pressure with the lower compression and keep the lift high for the head flow, when I built the short block I ordered flat top pistons from wiseco and after 3 months of back order I end up getting there reverst dome pistons so I could get the finished machine work done before stock car season started(if that happend the car would have been down for the summer) thats the reason for the low compression. Ryan even told me it needed more compression, but that will be the next short block. The short block was built 3 years ago and the heads,cam, and intake were done last spring.
