1)will the stock runners, plunum and base flow enough air,
Absolutely not!!!! It will physically work how it will be a dog at higher rpm.
2)how do I recalibrate the computer to accomodate a new fuel map,
With your set up you will need to have a custom chip "burned" for your specific application.
3)will the MAF flow enough air to satisfy this engine
It should, you can also hog it out a bit. Lingenfelter & TPIS can show you how.
4)how will the low vaccuum that this engine produces affect the computer
Be sure and use a camshaft which has a good vacuum signal such as the LPE 211 cam or the TPIS ZZ9 cam. Either of these would be an absolute killer setup for you.
My advice luke woulf be to put on a TPIS miniram manifold. It costs about $900, however, if you have any doubts about how effective it is, check out the November 1998 Corvette Fever magazine. With this manifold on a mild 350, a Corvette is running low 11's at over 120mph!!!!!
Good luck!
