Hi all,
Looking for some advice on an 7FB inframe. Goal is 500-550 reliable hp. Truck will be grossing 100+k lbs, 18spd 3.91 gears.
Was thinking the ipd durability kit, but have read mixed reviews on it. As it sits was leaking coolant into the sump so suspecting leaking liners but will know shortly. Pump and advance sent out for rebuild. Head will be out to be inspected and cut.
Will be replacing the nozzles ase well, wondering on that too. Don’t think I want the marine nozzles but not sure if the 460 had bigger then the 425?
If anyone has a recipe would greatly appreciate it. Engine vin is 7FB95319 425 ataac. Only real current upgrade is the turbo and upgraded radiator. Running a borg 0000 with a 1.45ar.
Thanks
