Block type Lie algebras have been studied by many authors in the latest twenty years. In this paper, we will study a class of more general Block type Lie algebra $\mathcal{B}(p,q)$, which is a class of infinite-dimensional Lie algebra by using the generalized Balinskii-Novikov's construction method to Witt type Novikov algebra. We study the representation theory for $\mathcal{B}(p,q)$. We classify quasifinite irreducible highest weight $\mathcal{B}(p,q)$-module. We also prove that any quasifinite irreducible module of Block type Lie algebras $\mathcal{B}(p,q)$ is either a highest or lowest weight module, or else a uniformly bounded module. This paper can be considered as a generalization of the related literatures., Comment: 14 pages. arXiv admin note: substantial text overlap with arXiv:1102.5187 by other authors
