833 Strength

Thank you guys for all the replys. I have toned down the build a little bit. I have not had the motor dyno'd yet but I would expect mid to high 600's hp and tq. I will be using a McLeod RST clutch and Hays Billet flywheel. My dart weighs approximately 3,300 lbs with me in it. Still think the 18 spline will be the weak link?
