I know some people still find it hard to believe I made 249 rear wheel torque...but...
When you consider I was on a Mustang dyno that's a few % below a dyno jet you get...

Just got my heads back.
I went to 1-3/8" but this was really overkill. 1-1/4" would be fine...up from 1-3/16"

#1: 100

Well, that answers every question about why my engine has been under-performing...
Now is not a good time to have to do a rebuild. Was hoping to wait until the spring. Also sprung a leak on the internal slave cylinder of the F40...
Just got the call on #4 & 6: 95 & 110...

Golden opportunity to step up to aluminum heads and make some power

Or a golden opportunity to explain why I lost power after swapping to a Trueleo + DIS...

Why would you hog out so much material on the floor of the port? You know there is little flow(if any) in that area? Unless you are adding boost?

Well, the inside diameter of the header primaries are 1-3/8" so I was just matching everything up...
But since you mean the intake side, I leave that to my machinist.[This message has been edited by lou_dias (edited 12-16-2014).]

Sorry, was talking about the intake. For the headers, they are built to match the engine, not engine built to match the headers, IMHO. Its going to need more cam now to get more out of the raised powerband, otherwise you may find its going to be a dog in the entire rpm range.
FWIW, raif's car my have put down ~250 lb ft, but if you look at the dyno sheet, the torque takes a sharp dive after the initial tip-in.

I went to the .480/.480 cam from WOT-Tech... Engine is now .040" over-bored...[This message has been edited by lou_dias (edited 12-16-2014).]
