ls1 vs 347 fox
my cousin just bought a slightly built 347 for his mustang. Dynoed roughly 420hp on an engine dyno. Got the engine in the car and everything going about 2 days ago but he hasnt received a dyno sheet or any information on where to shift it at.
Hes shifting appx 5500rpm in the video, my car is the camera car
my mods: bg ram air, lid, ported TB, ls6 cam (shift points adjusted to 6500) 3500rpm fuddle and a dynomax bullet. I have ran a best of 12.27@110mph

he was running 11.9@113mph pretty consistantly shifting 5500-5700. he was gonna try shifting about 6200rpm in a gamblers race but it got rained out.
