For quality, workmanship and performance, I will grant you that the MVVS engines are excellent products. I too owned one of the early MVVS Q-500 engines. Ran very well. Outperformed the Webra .40, and could keep up with the SJ-40 at the time on standard race issued Omega 15%. At the time, the exhaust system left much to be desired, and was its weakest link. Morris does a pretty good job of supporting the products in the US. I'm sure the canadian and european support is just as good.

However, consider this..... (to get back to the price aspect)
for an extra $30 or $40 ...... the engine owner can actually speak to or directly email the designer/manufactuer/builder of the engine, get accurate first hand information...... plus have a outstanding performing engine (SJ-46 for example for sport use)..... with an excellent exhaust system and leak free needle valve...... all provided with well documented operating and break-in instructions.

and..... as a result

this post would probably not have been necessary, or could have been answered fairly easily

For many, price is only one measure of the value of a product.
