I built a pump gas 10.5:1 400 for a buddy using AFR Eliminator 195 heads, and a mild Lunati hydraulic roller (243/251 duration .560/.565 lift). Its in his full weight, street driven S10 Blazer with 700R4 and 4.10 gears. He runs mid to high 11's on drag radials and regularly pulls the front wheels 6" off the ground. The engine is totally streetable and I would say it makes 500-550hp easily.
