perfect size, amount
Individually wrapped packages that are labeled. I wish I would have done that when I took it apart. Every nut, bolt, and washer was there, perfect size, amount, and perfect finish.

Use 6 point to prevent marking head up
Use on a 383 stroker for a 93 k1500 . Looks ok dont like the short head on the bolts. But that just me.

Works good thank you
I have a 1989 Pontiac Firebird with a 350 TPI and couldn’t find a kit for that so this TBI kit ended up working out really good. I lost a lot of bolts in the process so this kit really helped out and has a lot of stuff.

Wish I’ve bout them for all my previous builds.
Very nice setup for rebuilding an engine. Granted it doesn’t have bolts long enough for factory exhaust manifold but does have nice header bolts. I’m very impressed with the product you get as well as packaging.

Higher quality than expected!
Very high quality set of hardware for your small block chevy. Everything comes separated in labeled bags. Very helpful, However if you are expecting this hardware set to be shiny they ARE NOT polished. Just a flat stainless finish...
