Re: XR8 Sprint motor
To get much more power you'll need to rev it harder..to achieve the airflow required.
The Sprint/ Cobra engine had a small std cam in them, the 1:7 rockers made up for it. Infact the Cobra cam was adjusted to allow more torque at lower rpm..Good Crane cam,springs, port std heads Gt40, better inlet, bigger t/b maybe?? Exhaust as always..Like modding a 200 kw mill to 220...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
