here are the plans for my 289 going in my 66 mustang;
1: balanced rotating assembly, no blueprinting as it is a waste of money for a street engine. in fact unless you plan on a race only build up dont spend the money on blueprinting. balancing on the other hand is worth the money.
2: cast flattop pistons as this is a street motor, and wont see more than 6000 rpm.
3: world products windsor jr heads with 1.94in/1.50ex valves. the later jr heads have 1.60ex valves.
4: havent decided on what intake/carb combo yet, either a weiand stealth with a road demon 525, or an offy dual quad with twin 1.08 venturi autolite 4100's.
5: retro fit hydraulic roller cam from comp cams featuring .480 lift and 260 duration(advertised).
6: tri-y headers and dual exhaust with 2 1/4" pipe out the back.

all in all this engine should produce about 325hp when all is said and done. it will have solid low end and mid range torque and hp, but will drop off above 5500 rpm. i also expect this engine to get about 18mpg around town and 25 on the road.
