Well, I'm picking up a used IGT roller. What would you guys suggest as a good engine for a good price? I want something that really has really good top end. I was thinking about the ws7III but that is rather pricey. I have a line on an STS D21T with pipe both NIB for 100 but have heard they are a little spotty on quality. Aslo thinking about the axial 28RR. I dunno, too many choices. Would rather get new but would pick up used from a local if the deal was right. Any suggestions?
