A set of pistons on EBAY, item # 390053955739. These are Chrysler factory pistons, and are dished!! P/N 2084390. Are these the "truck" low compression pistons? |

Stock style pistons are cheaper at summit racing <$12 per slug. |

2084 390 = 0.020" oversize, export low compression. |

What are they...about 6:1 for a compression ratio?

Don't believe I have that specification! 7 or 7.5 stands out in my mind but that might be out of thin air. Someone would have to do the math. Seems to me these'd be a great pick for a turbo setup... |

The normal pistons are good for boost but if these are 7:1 then they need 40 pounds of boost!!

Get everything on the big side and you have a slug or get everything on the low side and it can run like a scalded dog.My 340 is 9.4 to 1...advertised 10.25 and a mid 70s smogger 360 I checked was something like 7.5 to one. |
