Re: 6.0 block See my sig. re 6.0 liter LQ4 427 Z07 Motor that MTI just built for my 98 C5. As i am staying N/A i achieved the 427cid via a 4.060 bore and 4.125 crank. If your going to spray or using other F/I, then the optimal set up is a 408 cid, with 4.030 bore and 4.00 crank!
Best of Luck,
MTI 427 Roadster
ps-If you do the big bore like i did must get block sonic tested to insure enuff cylinder wall thickness. With the .030 bore no reason to do this.
