magnum hds

The pistons are forged Fts @ -.003 deck ht.
Cam is [email protected] 105ICL, 111ECL, 108CL installed 3* advance, .560" I&E lift
IO22* IC52*, EO58*, EC16* It bleeds off compression big time at lower rpms, but sure provides a lot of snap above 2500. 430 gears help in that respect too.

With the magnums I will have .037" quench and 11.9 calculated compression w/ 58cc aluminum heads. I'll be CCing a couple of chambers tonight to make sure.
thanks for the feedback. :salute:
