Hello All I recentlly picked up a 348 tri-power for my 66 GMC. I have a wicked high reving 327 in their now and want more power and torque. The power train will be 348 to 700r4 to 12 bolt with 355 gears. I have inspected the bottom end and everything looks good. The cylinder heads will need a valve job. I want to build a mean motor for the street. I need a good choice on a cam and also what needs to be done to the heads to make this motor perform. Also any tips for the stock carbs I need to rebuild. Thanks
