I dont know if the Vararam is going to do any difference but for sure the dyno tune will. But just remember get the tune after you finish modding it.
mod's first . cam and spring will give you all you need to kick his a.s.s. OH then dyno tune
. if thats not enough then s/c it
cam $3-$4 hundred depending on what you get. i went comp cam
springs and keepers $280 give or take.(valves and heads are good for the HP)
new lifters(tappets) $250-$325.
hardened push rods $150.00 if i remember right.
new head bolts and gaskets, fluids
and a crap load of time.
or you could pay to have it done. labor cost $1500 to start. i do all my own work.
ever thing you need is right here. ask for Matt.
s/c on ebay about 2-6 K / new 6-8k magnacharger.
procharger not sure im thinking around 4-5K
installed over all 10k COULD BE LESS. again i do my own work.
dyno dyno dyno. i'm sure there are other folks out there that may very some numbers. but all in all im sure im not far off. cam is where i would start. that will give you the torc to pull his ass. and the extra hp to keep it.
