something definately not right, a 460 has more hp than a 440 period so why would you have not gained anything by putting the 460 on a 440 case. if you ported it too high you would have lost some torque. ive never heard a complaint on the hybrid more hp and lighter than the 460. jmho
Jacob - Have you've done many 064/066 conversions? Did you get similar results?
One thing I was able to do to give the 440 case an edge was to use a modified 064 piston.
Will be following this thread with a lot of intersest! I have a 044 with a BB that I have been wanting to put a 046 top end on. Is there any difference between a BB kit and a OEM 046 jug?
Yep and yep. The difference isn't as noticeable with the 064/066 but it's still there. Plus a person would want to make an effort to get the "improved" 066 crank with the 13 rollers in the big end rod bearing (although the failure rate on the 064 crank is low.)
The same effect is also present when converting an 056AV/Super case to a Magnum/Magnum II.
