A link to a 347 Stroker 500 HP, I think this is what your looking for? I was going to get the 363 Stroker 7K RPM pushing 575HP but it was $5k more in price. I paid $15k for my engine. I also added my engine build as well on the dyno, small but strong. I went for weight reduction and I was able to use my existing headers and side pipes with this motor.
