What is a street able motor (valve train) set of materials that could sustain 7k rpms ?
So, what valve material, spring materials, push rods, lifters etc. No ceramic lifters unless they are out on the market again. Rich |

I have a similar Suby combo now with a 104mm Nickies bore size and a destroked crankshaft. Its much cheaper to build than the Mighty Spyder was.
I have only built one engine that cost more to work with than the Mighty Spyder and it was a Fuhrmann 547 4 Cam Carrera. To build a hi-RPM T4 cheaper use a 66 stroke crank, couple it to 105s and spend as much as possible on the heads, then optimize them to the camshaft and valve train. |
