Re: Building a beast...doing a 391
If u already have cams, ported top end and heads, Dr. Greekenstein’s big bore motor is a pretty budget minded way of giving ur LT5 a very healthy boost in hp and torque.

Re: Building a beast...doing a 391
Where is Pete? Closer to TX than Marc? After my Miata engine swap, I’m super tempted to have my ZR-1 warmed up a bit. $10k for 500hp is a bargain compared to my Porsche or Mazda.
