Is this going to be a race engine where you need a sfi dated one???

I don't like fluid damper but i won't go into why because it would look like i was slammin them

I like the ATIs but they are ass holes to try to get say a ford pulley for 3 bolts --they use chev 3 bolt pattern which is like .050 off so you have to machine the holes correctly

We have been using sone powermaster and bhj also
