Hey all you smart 340 engine guys...

If you are planning to buy heads see if you can find a nice set of cast iron
W2's. Will make more power than edelbrocks. If you must have needle bearng rockers, harland sharpe's, jessel, or T&D are the only ones out there that will last. 3 or my frineds have 416 motors ranging from 556 hp (with edelbock heads) 580 (ported cast iron w2's) & 620 hp (ported indy heads) TTI headers are also worth the money as we picked up 20 hp on the dyno over hooker supercomps ( they fit better than hookers also) All 3 engines are pump gas motors & are driven on the street a few times a week.
