Specs of the whole car, or just the turbo?
Car does not have a WOT tune yet, so the Speed Inc. guys will see how that goes and see if they encounter any problems. There is a chance that the converter might not fit this new setup.

AllPro's are aftermarket head castings, not ported. But they flow pretty good, but are not crazy. I had been interested in ETP's but they were backed up pretty bad.

With that low of compression and stock cubes I predict it wont hit full boost until around 4500 rpm's? Will sure have one hell of a topend though. How high do you plan on reving it? To get the most out of that turbo and A/R you would think at least 7000 rpm's. Maybe would of benfited from a 5.3 liter crank maybe? Anyway very nice combo for what you will use it for!!!! I predict 900 rwhp with some race gas maybe a little more.
Oh what kind of valve train are you running all light weight ****? Hollow valve stems? Maybe titanium? What kind of rockers?

-Plan to rev to 7000 at this point
-No I don't think a 3.27 stroke would have helped at all, I'm even thinking the opposite for the next shortblock. I'm considering a 8.0:1 370-402ci setup. Over the years I have not seen any evidence to say that piston velocity and side loading etc. warrant us keeping the stroke down. But I'm undecided at this point.
-Rev springs, 1.7 non-adjustable Y/T rockers, Inconel exhaust valves that can take more heat..... 2.05/1.60 valve sizes
-900rwhp is possible not sure I want to turn it up that high without first making some runs. I'd like to end the year on a good note not broken.
