Horse Power and Torque

Marcohotrod the shaft was 5/8 so who knows why it failed. Also a big thank you to Mopar Tim as he hooked me up with a 7 blade fan, just had to pick it up at his place, which is all of 20 minutes from me. Got to see and hear his 69 GT Dart convertible and it is awesome. Thanks again Tim and I'll touch base with you at the end of next semester when the chassis dyno is back at the college.
AJ/Form S As soon as I get the new radiator in place I'm going to go back into the dist. and slow the advance down a bit more. As of now its all in at 3000 so I'll take your advice and have it all in at 3500. Headers on this car are not an option. So it will be cast iron manifolds and I'll be happy with it LOL. Some one else mentioned carb tuning which I have done. Upped the primaries on this Street Avenger 670 from stock of 65 to 69 and secondary side from 68 to 72. I also upped the pump nozzle from 31 to 35 and it cured the slight stumble it had when pulling away from a stop light.
