What hp and torque am I making?

Sounds exactly right. Dulcich did a supposedly everything stock 340 build with the 268xe and X heads with a 3 angle valve job and claimed 400 hp. That is what makes me think the Westech dyno is a little happy. Must have had some magic dyno dust sprinkled around that day.

OP's build will be lots of fun on little coin- what hot rodding is about in my mind. Need to get those stock 360 springs swapped out though to let that combo rpm like it can.

That's the next plan. Is get the matching comp springs and retainers. Quick question will the rotating retainer exhaust valves work with the new springs and all new retainers. I thought a long time ago a guy posted about the valve lock position was different than the intake valves causing the exhaust and intake springs to be different heights on the smog heads.
