Oh, that is screamin Woods W9 with that compression, you are going to need a cam with late intake closing and alot of duration. W9 with that compression and some head flow will nail 95 hp, maybe touch 100 hp and a rocket in the mid to upper rpm"s

putting 11:1 pistons in it is not enough you need to know bore cc's of pistons and heads deck height if you run a w-9 on anything less it will be soft out of the hole
example bore 3.498, .045 gasket, 19cc 11:1 pistons, 0 deck, 83cc heads,=10.39:1 that's not enough comp. for a w-9 you really need to know all these numbers before putting such a large cam in it you will be disappointed if you over cam that motor
here's a video of my engine with w-9 10.97:1 comp
