Your best bet is Mark at Precision Marine in Kenner,La(504-469-7463),he can do 600 or 640 pretty reasonable and dependable.He can dyno and tune the ECU and if needed fine tune it at the lake.Rob

Do a search on posts by "Linster" . He has done some nice upgrades to the guys local here in Richmond. I think he has built 6 or so 500EFIs into reliable 600HP/700TQ bulletproof motors with NO BLOWERS.
The Arizona Speed & Marine monoblade throttle body is a nice mod to start with. Then you need to talk about the ECU. After that, there is not much left without going inside, or supercharging.

I guess lower but it's been a couple years since I bought mine. This will give you a bullet proof setup with a nice increase in HP. If you get ambitious, look at cams. Short of getting blown, this is probably your biggest bang for the $. Just my .02

Each set of heads, polished and ported and built by someone who knows what they are doing...will run you about $5k all said and done. For both motors, labor, ECU flash...you are right around $10k as Ted suggested. I recently spoke with Dean Gellner about doing this to my motors...

Tyler crockett is supposed to be finishing bolt on plenum tops with a built in throttle body that is re-located, He is having these casted at a foundry and will have them on the market soon. In intital testing he made 630 hp on the dyno with other mods,Smitty

The biggest deal with this engine hangem, is getting the computer perfect. Go to an experienced builder. Even with a whipple, the computer won't be perfect, unless you can tune it on a dyno. I speak from experience.
Add a Whipple, dyno tune it, and your MORE than satified.
Then go buy a speare drive :-)
