i guess everyone wants to read but nobody wants to help

 

like you dont know where to start? that is a huge openended question. what are your mods now? 850hp with be SO hard to control on the road and be out right dangerous for anyone in the vasinity. this will be a VERY expinsive build expecially if it is to stay together 4 an extendid period of time. meaning its not a dedicated puller or strip truck that gets freshined up all the time.

 

what bout 700? i havnt done anything to it yet im goin to start with stage 2 cold air arp head studs fire rings 5" pipe turbo back and a edge juce with att cts then i was thinkin bout a 85% injection pump and 185 hp injectors what do you think? what else should i do or what should i do diff?

 

you will need a couple good programmers. when the head is of PORT IT so it will flow. you will need duel cp3's twins is absolutly in the works. making that kind of power on a singe would be unusable on the street. you will need a totally aftermarket fueling system.

 

don't waste your money on firerings or porting go with your ideas and like was mentioned above twins are a must something like a 62/474 or a 62/480 should be more than enough!

 

how can you call porting a head a waste? at the hp#'s he is wanting to reach it is almost an neccesity. not saying you cant get there without it but damn that is a far cry from a waste. air in air out man. just throwing parts or fuel at it isnt how you build a good running high HP anything! do it right...once

 

Do a little reading. dual cp3's, big twins, built bottom end (if you want it to hold past one dyno pull), big injectors, 625 arp's, firerings, (ported head IS a good idea and a custom intake). At the boost you'l need for that hp, then a good intercooler is a good idea. The cheapest way to get there is to skimp on building it up, throw an A$$load of nitrous at it, make a dyno pull and hope the rods stay in the block. All of this of course is just the beginning. Fill out your sig and tell us what you plan on doing with the truck. And make sure your checkbook can handle some pain.

an airdog, fass or beltdriven lift pump also.

 

Even 700 HP isn't going to be cheap.

 

250-300hp inj. nozzles, dual cp3s more with at least one being an 85% over. Mild head porting, studs will be a must. Fire rings are good insurance or you could get away with o-rings with the mls headgasket. aftermarket cam and valve springs. 5inch exhaust Smarty tnts/SSR and a ts mp8. A set of race compound turbos or a 68-71mm single with a little nitrous. Get a fass 220 or 260 pump. Get it tuned in on a dyno and you should have a solid 800+hp. Eventually youll be going into the bottom end, get a set of coated pistons, main studs and either 12v rods or rework your stock ones. Having cam bushings installed all the way through would be a good idea.
