[84ScottsdaleMudding]

I got this truck in spring and have been restoring it has a 350 v8 with a 4 barrel I think its a LT9. Mainly stock except a edelbrok air cleaner, summit headers, and a high flow dual exhaust I looked up the specs on it and it comes in at a whopping 165 HP HAHA seems a bit low for that kind of engine dosent it? When I step on the gas it barely dose anything is this normal for this engine?What are some good upgrades for this engine that i will see some HP out of I already have a edelbrok intake manifold for it just didn't put it on yet.
