The everyman's 360 LA Eddy headed engine dyno tested
My friends 70 Duster makes almost the same power, we have driven it to the track with 3:55 gears and a 3000 stall and ran 13:20 on small drag radials, full weight car other than a fibreglass hood.
13.2s are a PW of .080 at a race weight of 3300 that is 3300x .080=264 hp required. if you lost a half second due to chassis set-up, it would be .089, and .089x3300 =294 hp
Just saying
At 400 hp, that is 400/3300= .121 pw, and should go 11.6 with unlimited chassis. Add a half second for street chassis and you get 12.1seconds
But ET is deceptive; a better yardstick for power is the trap speed.
At 3300 pounds;400 hp should go 115 mph,294 should go 103,and 264 should go 99.
Don't feel too bad; 3.55s is the total wrong gear. You can easily trap in second gear with that. 101=6550 with 28" tires and 5% slip. That is not the quick way home. But worse is trapping in third@ 4500,lol.
For a trapspeed of 101, a better gear is 4.88s. These will get you 6200, pretty good Rs for a 268* cam.With slicks,SS springs, and that 3000TC, this will launch like a jack-hammer.
So the big question is; do you recall your buddy's trapspeed?
