Just got my 327 back from the exhaust shop, went with Hooker Aero Flow Chamber muffler, one-in two-out. It's an f-body style muffler. ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

Thanks guys! I think I need some carb tuning, don't think it's getting enough fuel, but it's running pretty strong for now. I'll get a full carb and ignition timing tune here shortly! ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

Sounds like an idling locomotive. Nice. ------------- Content intended for mature audiences. If you experience nausea or diarrhea, stop reading and seek medical attention. Located usually near Rochester, NY and sometimes central FL. |

Thanks everyone! I'm excited to get her really dialed in and possibly see what it does at the track! ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

Where did you find a cam blank, who ground it for you, and what are the specifications?

I sent them a factory 327 cam, have an extra laying around as well. Sent it to Oregon Cam Grinding: http://www.oregoncamshaft.com/ Went pretty mild on the specs because vacuum brakes and such: 206/212 @ .050”, 250/260 adv, .431”/.443” lift, 110 sep ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

I had them do a 327 cam for me as well, but I haven't swapped it in yet. Last time I was up there, they had a pile of 327 cams. Great guys over there. ------------- 68 Jeep Gladiator - AMC 327 w/ Rambler 4bbl, T18, D20 |

They did a quality job for sure! I haven't had it long enough to claim that the tappets haven't gone flat or anything like that, but no issues so far. ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

Sounds great. How does it sound at higher revs? And how many boxes are in there? Ivor ------------- 63 Canadian Ambo 990 V8 327 74 LandRover Lightweight V8 SIII Shopping Trolley |

It just hit high revs today, I'll get some exhaust clips. What do you mean by boxes? ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |

Stock 327 cam is 244* adv., .381" lift.
Stock 360 cam is 263* adv., .425" lift. Your custom 327 cam is 250/260* adv., .431/.443" lift. So spec wise, its pretty much a stock 360 cam and yet its enough to make a 327 lope at idle? Doesn't that seem a little weird? Definitely not a sound one heard every day. 327s have a very distinctive sound anyway, so the sound of a cammed 327 is definitely a new level of unique sound. I don't think any other engine out there sounds like one of these. ------------- 1955 Packard 1966 Marlin 1972 Wagoneer 1973 Ambassador 1977 Hornet 1982 Concord D/L 1984 Eagle Limited |

I mean how many silencers? My stock 327 has the single tail pipe and two factory boxes and it's very quiet, too much so for my taste. I like to hear that rumble. Ivor ------------- 63 Canadian Ambo 990 V8 327 74 LandRover Lightweight V8 SIII Shopping Trolley |

It's very mild, but it was running with a poorly tuned carb, I'll take another video soon and post it. It sounds fairly similar to stock now that tuned, but it's tuned around 600-700 rpms in gear at idle, 900-1000 in park or neutral.
Ahh I gotcha, I just have a single Hooker Aero Chamber Muffler. It's an f-body style muffler, so it's very similar to the stock muffler setup. I'll get some detailed pictures! Here's a little video of the setup: ------------- 2020 Ram 1500 Big Horn Night Edition 2000 Trans Am WS6 1989 Trans Am GTA 1989 Grand Prix ASC/McLaren 1983 AMC Concord DL 1966 AMC Rambler Rebel Classic |
