IHRA pure stock

It's to a large degree what NHRA stock used to be about 20 or so years ago - in addition to what has been said, stock valve spring pressure is a requirement. Do get a cam ground for it though, just let the cam people know what spring pressure, overlap, duration, and lift limits you need to follow. If you can't find the specs, one of the long time 428CJ builders on here can help you with them. Your combo should be quite competitive in IHRA pure stock, good luck.
