| Post subject: | Race Block and Head Choice - Which Years? |
I am going looking for a 225 Slant Six block and head to build an all out race engine. Is there a block or head that are the best choice? I am looking for a year model car and model the block or head would be in and the casting numbers to look for. How much could I expect to pay and are they readily available in the junkyard. Help! I am ready to get started right away.  bwhitejr |

The newer heads without the drool tubes are cast with more material around the ports. This means they can be opened up, or ported, further. |

You want a 1968-1974 head if you need plug variety, or a 1975-1980 head if you have the need to 'hog' the thing out... You will want a pre-1976 block if going forged crank (or need it for a 198 long rod mill)...you can still use a 1976+ cast crank mill for standard overbored buildups, check out the articles posted and you'll have to make some 'guesses and choices' on how you want to build it. -D.Idiot |

slightly off topic, but has anyone actually had a cast crank fail? not just a bearing, but an actual crank? given the choice I realize forged is the way to go, its what I have myself, I was just curious if someone has actually had one fail, in either daily driven or race application. I'm sure it probably has happened, I just haven't heard of it. |
