Hmmmmm,

Good info here...my 427 SO (Shelby CSX 4xxx)runs at about 15-20 at idle and 50 anytime I push down on the loud pedal....almost 10k miles on the motor. I also had a 427 CO with a stroker crank and it was a joy on the road ---- I almost had to beat my brother out of the car with a sledge hammer once he drove it, he still holds it against me that I sold that car.

If you are set on a rebuild keep the compression ratio at 9.5 - 10.5 and put in a stroker crank.....build a torque engine that will be pleasure to drive on the street. If your goal is a high HP racing engine that loves 5500 RPM + take the directions listed above.

BTW pics in my gallery of both cars....the silver Unique is the 427 CO.

One mans opinion........
