    What cam is that, a Lunati Voodoo?

    I'd say 395-410 @ 6200. You might do better with a 750 carb

    410hp @ 6100rpm was sticking in my mind as well, with a good tune. Probably 380 torque @ 4800rpm. Just a guess though.

    (You will post the numbers when it's done, right???)

    trick flow stage 2.

    I would be really impressed if it made that much power with that low of a compression.

    I'll post for sure. The dyno guys needs a 2 day headsup. We're gonna rebuild the holley bryant has and I'm waiting on valve covers and an oil pan to come in. Maybe just some other little stuff left to finish but then it's off to the dyno . . . it's a little pricey though, $450 to dyno it. Gonna be picking up extra shifts at work.

    Mild for a roller. I'd say you'd be hard pressed to make more the 400 hp then

    Just a thought (suggestion)... I would build it with around 9.7 :1 compression and use a 650 street avenger carb. It would make quite a bit more power and still be pump gas friendly.

    I should have mentioned guys,the engine is going to have a vortech supercharger put on it. So we built it with low compression. And I should add that I got a killer deal on a used supercharger. A V1 S-trim with all the hoses and brackets. I figure the headunit will need a rebuild and it's good to go.

    We went over to some cam shop in San Diego, the guy said the cam we have is decent. He wasn't the most thorough guy I've run into but still, he said he would run that cam for both the NA and once the SC is installed. The carb seems too small for when I get the SC, we'll probably go with 650-700 blow-through.

    What blow thru carb will you be running once you add the charger?
