These things don't run off stock gm computers either. They use a very expensive Bosch engine management system that allows them to do a little more than we can.

That sounds like a really cool project. I'd like to do one of those short stroke LS7's like katech sells (346cid) with a cam in the 270ish duration. I definately think its tuneable

That cam sounds nasty....but so do a lot of others. It all depends on what you can tolerate. If you don't plan on road racing, then there are a lot of nasty sounding cams with better street manners. Like I said that cam will probably need to idle over 1200 rpm. That's not ideal for a street car.

As far as tuning goes...if you know what you are doing, you can tune just about anything. Me...I'm still learning.

To answer your initial question: yes the cam is tuneable.

DPs are allowed up to 4" bore. L92s are budget heads. Lots of better options out there. The Tony prepped AFR 205s seem to be the most favorable (flow outstanding below .600).

Oh ok. That bottom end was made to fit rules for a light race car. Its in no way going to be optimum at all for what your doing.
