I am taking a class at the local college regarding 4 cycle gas engines. As part of it I am rebuilding an old 350 Chevy block. I am having the machine shop bore it out so I can make it a 383. I am looking for power and torque not high end speed. Any cam recommedations??? Also, I am installing rebuilt heads.....should I go with roller arms are the basic OEM solid arms??? Any other recommedations from those that have done this are welcome!!
