Spent 4 long nights last week pulling everything apart...installed new Patriot Gold dual valvesprings, Comp chromemoly pushrods, Powerbond 25% underdrive pulley....and a Patrick Guerra custom grind cam (231/235 .617/.620" 112+4LSA).
Started on the first crank, oil pressure built right up to 40psi. Drove it around the block a few times to heat cycle the valve springs so it would be ready for the next day.
Next morning (Saturday) I woke up and drove down to Diablosport and had Johan dynotune it. Final numbers were 435.5rwhp and 401rwtq - and averaged 26.5mpg on the way home.
Spins the 335s from a 50mph roll with my 300+lb friend in the car and a full tank of gas.
Videos will be up soon...
