252wheelieking Posted November 1, 2011 Report Share Posted November 1, 2011 I am looking to buy a 421 cub. If anybody have a good used 421 cub topend, complete 421 cub motor or 421 cub topend with 4mil crank I am interested. Pistons & domes would be nice if you could add them with the topend. Please dont try to sell me a used cub for new cub prices. I can always buy new if that's the case. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
