I just picked up a used shortblock for my Excalibur project.
It's a Dart Big M tall deck block with an Eagle 4.25" crank and 6.535" rods.
Right now it's at 4.530 bore and could use to go to 4.560.
Originally I had planned to just re-sell the Eagle stuff but with my ever shrinking budget I'm wondering if I could use it.
How much HP can it handle in a twin turbo pump gas 555 ?
