383 Stroker?

around 2000 i wanted to build my 383 and wound up using the 440 steel crank and resized ly rods. 30 over pitons had to be custom made at that time. it is a 431, 9.2:1 compression stock rebuilt 906 heads torker intake 1 3/4" headers 3" exhaust 9.5" converter 3.73s and it has gone a best of 11.81. i just made some changes and am curious how its going to run. stealth heads rpm intake 2" headers and a new exhaust. i dont want to put a bar in this car so ill gladly slow it down with gear and carb changes and make it more streetable while making more power.
