    9 seconds on a 'stock' small displacement block and drag radials?  :naughty:

    I for one am impressed

    With 14:1 compression what kind of fuel is that?

    It's funny how you read the build, and think, Man that seems like a pretty easy combo..Nothing crazy...But I know there is a lot more to it, it ain't just bolting some parts together to run those numbers..

    We ran that engine on C-14.
    ............. Best times came when shifting it at 9500.

    Class rules dictated 3" outlets on the exhuast.

    Heres a 9.60 vid with that motor.

    i just think that is bad ass. i would love to have seen your car run in person. was wondering what kind of maintnence a motor like that is for a season. did it beat up alot of valve springs and bearings?

    Oh -- sorry to hear that.  I mistakenly thought that something good happened.  Hope he gets it back together again soon -- and faster than ever . . .

    I know this post is old but it is an important topic when looking at Rich's combo.  This didn't happen overnight.  It's the result of YEARS of hard work.  This also wasn't some combo that just made a mid 9 second pass.  It held up and ran competitively in a class.  There's a HUGE difference between a guy who makes some passes at the track (like me) and doing what Rich and his team have done.

    There was never anything "on it".....all my engines run naturally aspirated.

    The 306 was pulled at the end of the 2007 season and replaced with an 8.2 deck 360....that was the motor that ran in the 9.30's-9.20's.
