Well, the magnum headed one Dulcich did years ago, that made 400hp...... made 382tq.
And the 420hp 360 I had on the dyno last year made 419tq.
340hp 340 made 378tq
331hp 360 made 367tq
I’m confident a mild 318 making around 320hp isn’t going to push the tq needle into the 450ft/lb range.
Not on the dyno here anyway.
