had almost the same build in my convertiable and had 280hp at the wheels

Mine's only a 327 not 347, but I have similar specs and last chassis dyno was a nickel off 315 at the rears (313.4), but mine is a manual. I lost a bit of top end power becasuse I swapped the standard Victor Jr (which wouldn't fit under the stock bonnet) for an RPM Air Gap and kept the Tri Y's, so torque was way up, but last 1,000 rpm, the Victor Jr would have pulled more, I'm guessing around 325-330 at the rears, but I'd rather the hefty lift in torque and no loss HP disadvantage under 5,000 rpm.

Cheers Bee
