Do you have a 440 or 400 block? Whats your budget and how % of street time? What are your goals and what car do you plan on putting this in?

I have used t he 440 scource kit in a 400 and am extremely pleased with it...not the 906 heads I used are wildly modified and flow exceptionally, also use this as a street car but it gets me in trouble.....fast and a tire eater have fun..

Most people dont like my opinion, but the wedge 512 kit is not a street engine. The largest i'll go in a B is 3.915 stroke. That's because the pistons get so short you can't build in a good quench, the rings do not stay stable, and simply put, they wear out very quickly. The oil rings need a support rail because the pin goes thru it. They are fantastic race engines. Not good street engines. Plus, it is pretty easy to get the same horsepower, with a little less torque for better driveability with treaded tires. You need a serious set of heads in any event.
