Those look like the '69 '148' chambers.
Does anyone know the chamber size of stock '148' heads? I've seen a lot of conflicting info. |

Thanks. I love what you are doing with peanut ports. Wish they made them with early 100cc chambers, as they seem like they'd be perfect on a 396/402. |

I should clear something up -- the 063s are NOT peanut port. Peanut port heads are normally found on truck engines to build goobs of low RPM Torque. 063s have larger oval ports. TAZ

The only thing I need now is one of your carbs, this summer for sure! |

I'm building a stock appearing 427 with some of Mark's ported 781 heads
Cant wait to see the results On 4.0 stroke and smaller builds, does the windage issue show up early in rpm's , or just 4.25" stuff and up does the issue really manifest itself?
