170 tips for a budget!

It's been argued (and a good one) that the 170 is perhaps the best slant, because it is an over square motor. That means the bore is bigger than the stroke is long. That makes for a snappy engine. I've driven both in stock form and IMO the 170 zings up in RPM quicker because of that. That means they get going quicker. The 225 would win out, but further up in the RPM range. The 170 with a 2 barrel and 2.5" exhaust would probably be a really snappy daily driver. I would not do the 2 barrel upgrade without the bigger exhaust, though.
