What do you guys recomend for a street car. A vacuum or mechanical advance distributor?? I just replaced the lifters in my engine and was thinking of trying the stock distributor over the msd #8582 as it is still out for repair. Iv'e read some posts that say I will get better throttle response and gas milage from the vacuum distributor. Would there be any problem using the old stock distributor and gear with my new cam??
