Tony;

I'll echo everything RallySnake said..... A couple of months ago my stock Duraspark distributor broke and I decided to upgrade to an MSD unit,I already have an MSD spark box.. I called the MSD tech line for info and the tech said for a street car they DO NOT recommend a mechanical advance unit,they recommend them for RACE ONLY vehicles... My car is a street car so I bought the vacum advance unit and love it.... Off idle acceleration is very good and so is the top end along with very good gas mileage.... There is no comparison between the MSD unit and the Duraspark unit,not even close.... I'm also running a 351-W..
