Hot Rod 340 builds and dyno test.

I'm not buying it.
My totally stock 1970 Swinger 340, in 1971,with about 12000 miles on it, went 98 in the qtr, which I think is representative of most all totally stock 340Darts. At 3330 pounds that is 246.66 hp, according to the bulletin book. So either the scales at the track that day lied about me and my car being 3330 or I remember it wrong. I was 130 back then so even if I gross the weight up to 3460, the power comes out to 256.
As an aside,thru 3 gears (3.55s) from 25 to 85mph, that car was one of the fastest cars around,in my town,bar none. ( after 85mph. the BB cars would start to overtake me, and by mid 90s I was getting nervous. By 100, I was occasionally seeing rear bumper. So I made it a point to not race past 90,lol)
If my 340 had made 320; then @3330#, it shoulda gone 108. At 3460 it shoulda gone 106.

HR says that engine was "nearly stock spec"
I call BS, with a capital BS

I say, put that engine in a chassis and run it up the track and see what's what.
They even tell you; put
