1972 dart 318 want to make the tires spin

Get the initial timing set properly and your total timing number. If it's got the stock timing specs for idle advance, that's part of your issue. Bigger cam will require much more initial than the stock smog spec timing suggest.

IMO, If that doesn't have at least 14-16 initial it's not close to right. Going to require some adjustments inside the distributor to keep your total timing number in range.
