Dropped my third member today to see why my rear ARB was non-functional. Found a problem. Fitting was probably fairly old. Never seen an ARB with a blue plastic air hose internally. Anyone know if that's how they were set up back in the day? |

That's some 1st Gen ARB there. |

Picked up my heads from the machine shop yesterday. I'd thought they were Explorer heads, but it looks like they're actually off a Cobra or Lightning, as they were already drilled for a 351w and the casting numbers indicated that they're somewhere around 61cc. Have to give a big shout out to Western Engine, as they IDed them, steered me right on whether they should be milled down, and then did a great job for a very reasonable cost and fast turn around. These guys will be my go-to for any future engine building projects. |

Early GT40s were said to have the larger head bolt holes and smaller chambers. This being said go have been the case because they were left overs/replacement parts for the Lightning line left on the shelf when the Triton motors came on line in 97. |

I see your F3ZE-AA part number. Is the casting date still visible after the milling? I can almost make out a "?609" on the top of the right head. |

SCORE !!! I just had the XJ head reworks by Western 6 months ago. I really like their service/work. |

Interesting. The date would suggest that they're not cobra or lightning type heads since they're cast after production of both ended. So why would they have already been set up with 1/2 holes for the head bolts? |

Post subject: | Re: Justin's retroactive build thread |
I've seen quite a few early 97 Explorers that had GT40 heads with 1/2" bolt holes. I have no idea why though. |

Huh, odd. Any idea on combustion chamber size? |

Post subject: | Re: Justin's retroactive build thread |
I've heard everything from 58-66cc depending on the source. Most seem to point towards 64. |

Shoot. Sounds like I need to try ccing them again to confirm it. |

Finally got some time to wash and paint the block. Still needs some work with a razor blade, but it came out nice. After some reading, decided on the earlier Ford blue with cast aluminum/silver front dress and intake. Haven't decided about the timing cover or heads yet, but am leaning towards the blue. Need to get the pan and valve covers in for blasting and figure out whether I'm going to spring for a different cam, then I can start getting this thing built! |

That's looking good. Can't go wrong with Ford blue. |
