.030 over 440 10:1, light weight rods, aluminum heads, RPM intake, Mopar 557 solid (or like cam) headers, HOLLEY 850 DP (note a Eddy 800 will not support a 500hp motor w/o modifications) That should get you pretty close.



huh...better not let AndyF's 580HP 406 (.030 over 400) he built with eddie heads, a small roller cam, eddie RPM intake and 800AVS know.....

BTW, an XE275HL is 231@.050

I was assuming you have a solid short/long block that you were going to add onto. if cyl taper is good, you could maybe get away with reringing your shortblock and calling it good.
