Just noticed on the last pull, he points out the oil leak at the back of the manifold, and on the dyno screen it looks like his fuel pump can't keep up as it drops from 313.7 lbs/hrs @5900rpm to 303.7 @ 303.7 oh and on the screen he's 4.9psi/5.5psi. I'd guess it's a touch lean, as I run all Holleys @ 6.5psi. I also don't like the massive jump in temp from 151 to 168 degrees- most of his engine videos seem to show this---I think it's his water setup as the cooling tower shares its water with the absorber. Looks like a flow issue or not enough waterpump supply to the dyno. J.Rob
