There is another way to generate the compression ratio you are targeting and it will not require pistons with domes. Get a $200 Skat 3.75 stroke crank some flat top pistons and build a 383. I personally don't care for dome pistons because of the flame travel characterisics making them more prone to detonation problems. The 286 magnum with the vortech heads or ported DBL humps make an exellent low cost combo for a hot street 383. American speed makes a crate 383 that is very similar that makes some thing like 450 HP and 500 ft lbs. BTW if you go the popup 350 way, be sure to check for piston to valve clearance carefully and allow some budget for possible piston machining. The duration and lift are getting in an area where you could possibly run into problems. Good luck!
