Your cam is mild though. This guy wants to get more aggressive than you do.

400 hp with 700 is not going to happen, unless you spray it. i would just do bolt-on stuff speed engineering has header for 230 plus shipping, shorty dont do much. under drive pulley, junkyard e-fans, trutrac with 3.73-4.10 gears. or just save little more go ahead and do the 80e swap.
