The 727 in my Hornet supposedly has a 6 cylinder converter which supposedly should stall higher behind the 360 with significantly more torque. I understand the school of thought here, but I’m wondering if anyone has experience with this and what their impressions are. I drove the car for a week before buying it with a stock-ish rebuilt 360 in it and it did seem to be a little looser than what a stock converter would be. I now have my more “warmed up” 360 in the car and am wondering how it’ll feel. I ran a B&M Holeshot 2400 converter in a TH350 begins this same engine in my Javelin that stalled around 2500 and I loved it for an all around converter with my 2.87 gears. ------------- 1969 Javelin SST "Screamin' Banana" - Totaled Feb 2018 1973 Hornet Sportabout X "yellajack" - 360/727/TracLoc DAILY DRIVER |

Coming back to this thread now that I’ve got 1,000 miles on the Hornet with my old 360 and the torqueflite with 258 converter. I was hoping to see about 2,500 stall. Feels like it’s more like 2,000. Anyone have luck with any off the shelf converters or rebuilders? ------------- 1969 Javelin SST "Screamin' Banana" - Totaled Feb 2018 1973 Hornet Sportabout X "yellajack" - 360/727/TracLoc DAILY DRIVER |

Josh, I highly doubt that that is a 258 converter. We can't even dream up a shade tree job that would get a 258 converter to match up with a 727. My guess is someone is mistaken. ------------- 73 Hornet - 401EFI - THM400 - Twin Grip 20 |

That’s correct. I’m putting out quite a bit more torque than a factory 258, so in theory, I should be flashing this thing at a higher RPM. However, I’m a lot lighter, so once again in theory, that may negate a lot of it. At any rate, the butt dyno says it’s around 2,000 stall give or take. ------------- 1969 Javelin SST "Screamin' Banana" - Totaled Feb 2018 1973 Hornet Sportabout X "yellajack" - 360/727/TracLoc DAILY DRIVER |

Ideally, I’d have the $$$ to install a gear vendors overdrive, 3.31 gears, maybe a Summit 8601 cam, and have a converter built to about a 2500-2600 stall. That’d be a lot of fun to daily drive and occasionally take down the drag strip. ------------- 1969 Javelin SST "Screamin' Banana" - Totaled Feb 2018 1973 Hornet Sportabout X "yellajack" - 360/727/TracLoc DAILY DRIVER |
