azfordman They are doing a buildup in the magazine for march 08. Using the new boss motor and the better AR heads. 340 cid maken 600 hp. Large solid roller cam. You could drop the cam size .100" and still make better than 500 HP. Something you might want to check out on the web or barnes and noble.
I sure the build is done you might want to call the machine shop that built the motor and ask all the good questions,
Tell them you are interested in building one and looking for info on their build up.
