350 hp out of a fairly stock 340

My mild 360, .040 over, around 9:1 cr, stock stroke, stock heads, hyd flat tappet cam, with an Edelbrock air gap and 750 carb, running a .444/.467 cam, TTi headers through a full 3 inch exhaust and a 727 trans and 3.23 gears in a full steel body, full interior 1970 Dart ran 13.80 @100 mph 1/4 mile.

I don't believe that motor made more than about 350 hp.
More cam, gear, and a stall! Lol! Just messing around! I'll bet She's a Bad Ride Man! With that combo you have, I'll bet She's a Highway/ interstate Beast! And Quite Streetable, with no issues!
