The 6.9 is tried and true but the 7.3 takes better to mods therefore i would take a little more time looking. that being said turn up the pump, turbo, delphi G code injectors
custom exhaust(mandral bent) gauges, gears (4:10) and lots of paitience

 

no on the g codes. they are smog injectors for the turbos. code bb flow the best. and if u are saying the 7.3 idi takes mods better, wrong also. 7.3 idi is just a bored out 6.9.

now a 7.3 stroker, yea. more expensive to mod, but does take to them better.

 

how whould one make a 7.3 stroker out of a 6.9 block diffrent crank and such ?

 

well the 7.3 stroker is a completely diffrent animal. the 7.3 idi is a bored out 6.9 with bigger headbolts.

 

oh are you talking about a 7.3 powerstroke ?

 

Hey riddick01, did you ever go look at that 6.9?
