[DeTomaso] Fw: 3RD & FINAL DYNO PULL

[Mad Dog Antenucci]

Hey Will,
  Its now at 381ci, still Cleveland block.  The cam is all most the same specs as the last engine 2 years ago (Comp Cam Hydraulic Roller#32-651-8, 245 duration @050/.612 lift)....the 302B alum heads which i bought from Dan Jones about 6 years ago had already been ported and polished by previous owner...we just cleaned them up. Dick port matched and polished Kelly's intake and we put the same 180's back on.

How fat is your cam? You're still at 377ci, correct?
