Further recommended upgrades

#28 Injectors (26.37 @ 55psi on 2000 and newer 3400 engines) $100 while supplies last
- Adjustable FPR for 1999 and older 3400s $135

Tuning. Local dyno place is $75 an hour to rent their mustang dyno and the dyno operator is very good with OBD2. Currently no tunes are available off the shelf. For those with OBD1 and swapping in a 3400, the OBD1 tuning service would be worth checking out.

Bottom End Recommendations

Stock. Free and if your engine is in good shape already, there is nothing to worry about for a performance street application using the above parts. However, if you want to go further, this is what I recommend.

Diamond Forged Pistons.
Sealed Power piston rings
New Tri Metal Rod and Main Bearings
Crank Scraper

$793 Regular price

Optional Teflon Scraper upgrade +$92

SS cam might be pretty good for the nitrous but I will have to take do a few simulations. The double roller set is all TCE, nothing GM. The GM 1994 3100 set is its own deal, and is the best you can get without the crank/timing cover work and galley plug grinding for the block. Everything looks good for your build. Nix the head bolts, since you have the head studs listed later.
