Anybody ever swapped out a heavy( stock) rotating assy for lighter aftermarket?
So, the question becomes.......
How much quicker does it need to go to justify the expense of a new rotating assy(that doesn’t include more cubes)?
I feel like you’ve already made your mind up on it...... so how much quicker does it need to go for you to say “mission accomplished”?
If you had read my earlier post you would have noted i would be happy if it dips into the 10’s. It will.
You seem to be ignoring why i am looking to do this.
The motor( at the end of this season) will have 4 racing seasons on it. I race a lot. I also street drive it.
Its due for a freshen up. It current has stock factory rods and factory cast replacement pistons.
To add nice forged zero deck flattops( raising the compression a couple points) and scat rods is about 1k, plus gaskets, bearings etc, that would be needed at any freshen up.
So i am adding 1000 bucks basically to a standard freshen up, plus a balance job.
I gain better compability with my current cam and convertor, better rods and rod bolts( piece of mind), and a fresh motor. And less bobweight
For the extra grand, its great bang for the buck.
