Don't have to be an engine builder or a machinist......it's a matter of imagining the possibilities.....remember not alot of people think a "teener" is worth the time and trouble to build, they would rather step over a "teener" for a 360 or the Holy Grail a 340, OR if some one is contemplating a "teener" build they get badgered to go the 360 route "just because". IMOP a "teener" is a great little engine; I took on a 427 Camaro with one just because I could; they are worthy what ever time and effort some one wants to put into one. Just because you've never heard of some one putting 2.02's into a set of 302 heads doesn't mean it hasn't happened, not every one in the world comes here for their daily dose of Mopar
