Ya know gang, these 413's don't run worth a dang with 5 & 7 plug wires reversed! Decided to detail my engine compartment on the 64 while I had the hood off (I had to take out the AC Evaporator) Somehow I reversed the wires and the dang thing would barely pull itself. MUCH better now. Back to her old smooth as silk self. My 2cents on the 440/413 thing, I've got both and both are FINE engines. However, the 413 is MY favorite, kind of like why most Che*Y people will admit that the 327 was the 'best' smallblock. It's a combination of power, torque, and drivability. Every 413 I've driven seems smooth as silk, no stumbles, lots of torque, plenty power. The 440's have more power but seem a little closer to the 'edge' unless it's in perfect tune, ie they might stumble a little off idle or bog when flogged. Of course my 440 has a Thermocrap which is probably part of why the 413 seems to have better manners. Kerryp __________________________________________________ Do You Yahoo!? Yahoo!
