327 head combo package

I was thinking about installing a head combo on my '66 327, and it's kit # Dart 01110003 or Dart 01110002 from summit racing website. It does'nt tell me what kind of H.P. I could get out of my 327, but I want it to be 400 H.P., and it's just for street driving. can somebody tell me what kind of H.P. I could get from this package?

thanks for your help

That looks like a pretty good combo however it is primarily designed for high rpm horsepower like over 5000 rpm, I think that the 215cc runner heads would be better suited to your needs but it still won't wake up until really late.

With the cam that you will need to run to take advantage of the RPM range of this package street driveability will really suffer. And you have a big single plane intake which generally will hurt performance on a small cubic inch v8 like yours.

This package would be better for a racing 400 rather than a street driven 327.

I would recommend the dart 195cc heads and a performer RPM style intake (dual Plane) with a cam that is in the 220-230 duration at .050 with around .500 lift.

This will really wake that 327 up and still retain the street manners that you are looking for. And you should be right around 400 hp.

Check Chevy High Performance- this months issue- they have a 391HP 327 build. I would suggest using a different cam, something with a little more lift, but the 1.7:1 rockers help make up for that... I woul dsuggest going with a magnum 268 cam though, the XE series is too agressive and has a lot of lobe failures.
