Well that also depends what the basecircle is on that thing. I don't know if it is more than .100 less than stock.

I went with the TSP hardened pushrods that came with the cam package for my MS3.They are 7.400 and they really didnt give me the sewing machine effect like i was expecting.

I would still go with the 7.425 if you havent purchased them yet. Im milled .040 with 7.400 pushrods, so thats like running 7.440 pushrods on stock heads. Im happy with my valvetrain. Much quieter than it the 7.4's were on stock heads.

Yeah I want TSP to comment on this.

I am placing a order and should I do 7.400s or 7.425's.
Spraying the car also.
