Weekend driver for the most part, there is a track less than ten miles from me, but more than anything just want to drive it to work some, and a trip around the area on the weekend, while trying to harass the occasional import. |

I would use at least a 3000 stall 10" converter and a 3.91 gear. |

I would run duals back to the transmission cross-member area and then Y them together into a single pipe. I would also use a larger carburetor. |

...and more compression (that stick likes it up past 9.5 to 10:1 and higher on the rpm band).... and maybe index at +6.... and port the head so those valve sizes don't go to waste... duals per Josh's recommendation....390 cfm holley or 500 cfm for daily driving.... 500- 600 cfm for racing.... 3.23 daily driving would be OK.... my car really liked that setup with 3.55's even with the OD gear... EI and recurved distributor is a must small 4 barrel, more compression ratio, porting, large valves, per your post should ring in about 190hp at the crank...with Dennis's gearing and TC, 16's in the 1/4 for a not so sorted out car...closer to high 15's once you get everything dialed together or better.... If you did it right, the car will feel like a peppy 318.... |

I like your buildup specs quite a bit. Dennis has got the combo there - 3000 stall and 3.55 or 3.91 gears. The Holley 500 2bbl is a great street/track carb for your kind of combo. Some head porting, at least in the bowls, would be advised as well, as DI said. Best, Lou |

With all due respect to those posting suggestions, you can't possibly determine a good gear ratio without knowing how large your tires are. |
