im looking in to doing a cam swap in the next 6 months and not sure what cam i should go with. i want it to have a choppy idle but be streatable and not kill fuel mileage to much will have pcm retuned for cam at time of swap. here what i have done so far

fenderwell intake
speed daddy headers no cat
180* tstat
ported exhaust on heads
3.4 mod pulley have a 3.2 pulley also
autolite 104 plugs
zzp 1.0 pcm
ported m90
2650 stall converter rebuilt trans


future plans are moded intake with intercooler, gen5 blower, new rockers and push rods, would like to run mid 11s in the future
 


Pick the XP cam then.


A canned ZZP tune will not be what you want, it is impossible to predict the needs of the engine with a canned tune on a cammed/ported cylinders heads engine. All they do is load a random set of numbers into their tables and hope it works. A custom tune is pretty much the only way to go with the mods you have planned, you will also need a wideband o2 sensor to monitor fueling.

Also just know that you will likely be the max range of both the stock MAF sensor and stock injectors with this setup.
