340 Build Up

No aluminum heas, find a set of W2 iron heads, fullu port them and run just shy of 11-1 compresion. You'll need about that ratio to run the big cam to make the power. tti has W2 headers that run under chassis with 1-7/8 tube size for good flow. I'd look into a roller cam and durations starting @ 260* @ 050 wi.600 + lifts.
