46MM? I vote twin 67's. Ditch those long tubes and go for the twins

I wonder what 6-8 psi would do to a 323 with the supporting cast I have?
That's significantly more than a 330 inch GT500 makes with the same blower, more boost, and better heads.
7psi with my 322 produced 587rhwp on E85. That was with a M122 blower. 12:1, FRPP cnc heads, custom cams that are basically 127500 locked out at a 108 icl with 113lsa, and stock cats. IIRC that was with 23 degrees of spark advance at wot.

CR, CR, CR.... 5.4L has 8.5 CR IIRC and 8-9 psi

I think there is something to be said for the larger bore helping with the combustion process.
Picked up my ride on Saturday. Keeping the revs under 4500rpm for the first couple hundred miles or so. I'm also trying to do as much compression braking as I can to help seal the stainless steel rings. Going back in 500 miles for the first oil change and evaluation. If everything looks good, we'll put it on the dyno and tweak the tune.
As an aside, when I arrived, the guys at Pro Dyno were all hovered over a blue S197 like a DOT crew. Turns out a Battle at the Beach competitor was getting some tweaks preparing for the dyno competition when the double keyed balancer let go and took a chunk of the crank with it. 1300whp has a tendency to do that from time to time.
Mustang Week in Myrtle this week. I may have to sit it out this year since there is no way I could properly break my motor in with that high level of testosterone floating in the air.
So how is it now?
