In my opinion you would be better off running destroked 289/302. The 255" crank won't handle 6000+ rpms for 3 miles to the traps. Use the strongest rods you can find. With a 4" bore you can use heads with big valves, a must for high RPM power, and I don't believe they would clear the bore on a 3.68" bore block. Remember that engine is going to be winding up for 3 miles, not 1320 feet. I wish you luck and hope to see you on the record page.
