My current combo is an early 64 390 block with the nubs that was cross bolted, filled with hard block and then bored to 4.130 and lined honed. It has an eagle crank, rods, weisco 13 to 1 pistons, Crain roller cam and lifters, ebock heads fully ported, with 2.15 and 1.72 valves, Crain springs, victor intake ported to match the heads, msd ignition. Use a cobrajet c6 with a tci kit and brake. In my mustang it has run 10.19 at 130 mph leaving at 3500 and shifting at 6000.
