Hi Guys
Just thought I would post a link to my 429 Boss genuine Nascar engine on the dyno at Brennan Motorsports. It has been fully balanced etc and tuned for pump gas. It will be going into a Tasca 429 clone once the car is completed.

I thought this may be of interest following the Ford 429 Boss mustang discussion. On pump gas the engine produced just over 700HP.
