there not the best choice but they will work.

They will be hot and smokey, IMO if your gonna run 370's you also need to use thin injector washers

if your gonna keep the stock charger and trans ( if its an auto)

I think your best bet would be a set of injectors out of a 96-98 with a 215 pump.

IIRC your injectors should be 5x.009 the 96-98 5 speeds had 5x.010's

hp is going to depend on your AFC set up, timing, along with many other things.

you could add a boost elbow, there cheep and super easy to install. the adjustable allen head in the elbow allowes you to regulate the pressure going to the wastegate allowing it to stay closed longer.

just saw you have a 5spd ... so you should have the 175hp injector pump. before you buy a set of injectors you should play with your fuel plate, air fuel control, and invest in a set of gov springs. these mods are all free ( the gov springs are cheep but sadly not free) and they make big differences in how your truck will run.
