I was just trying to see whats out there.My current combo runs ok for what it is.I have to make a call on a torque converter and just deciding to change the motor or leave it as is and work with it.I have flowed my heads and they were 268 cfm @ 600 lift.I ported these and they seem (for a home job) they work ok.My combo is a 410 10.5 to 1 (180psi)with a flat tappet solid cam.My car is 3150# w/driver.I have been 123.77 mph with this set up.My best et is 10.95 w/1.53 60 ft.How fast can a car go if it runs 122-123 mph in the quarter?This is pump gas w/mufflers.
