Hows this combo sound ?

Dave I have seen these motors box stock in the high 11s in a well set up car. They make closer to 410 horse then the 380. I have also seen the 300 hores version in the high 12s in 68 Dart. This was a street car with full interior, 2.25" exhaust and small 235-60-15 drag radials. Im sure it takes a ton of tunning to reach thiose numbers though.

Also the cam specs are

288/292 advertised duration
245/248 @.050"
.501"/.513" lift.

not sure what the LSA is though.
