Power upgrades

Well in that case....
66 with 6x.013's if you stick with the stock injection pump...
otherwise go BIG or go home. p7100 6x.018s etc...
trying to be competitive in a vp44 truck in sled pulls is a long shot as the vp44 and VE pumps are both the serious underdogs.... p7100 12v's and common rails have a clear fueling advantage

pro: more tolerant to abuse. does not require fuel lubrication, massive fueling potential, cheaper to gain performance from, can be made to rev up to 5k rpm.
con: static timing, can't be tuned on the fly, if you bypass fueling safeties it can potentially be tuned too much and cause a run-away diesel. (as in it keeps fueling and even after you kill the ignition it still doesn't shut down and keeps on revving. basically have to choke off the air intake to kill it at that point.)
converting to p7100 also costs as much as replacing your vp44 3 times. so if you are doing it just because you had a vp44 fail once, you are throwing away money. but if you are doing it to fuel past 650hp, then it is worth the money.
