Inliners International Forums General Discussion Engines New member with a 250 vs 292 question

Thanks all - the 4200 looks like an interesting option, but I think i will be going a bit more original with this first build. If the only thing I am buying with a 292 is torque I will stick with the 250 given that they are easier to find. If I am looking for more HP out of the 250, does lumping the heads make a huge difference?
