440 build 500+ hp build

I wouldn’t call that a “crack”.

To me, A crack implies it was once whole, and now the material has been over stressed....... and now there is a crack where the material failed.

I would call that more of a “fold”, where the material ended up with that small void during the forging process.

In any case, I wouldn’t use it.

I’m probably just cynical....... but I’d prefer to buy rods from a source where that was a major portion of their business model....... not just one of thousands of items they sell.
Thats not to say you couldn’t have still found one like that from Eagle, Scat, K1, etc.

I agree with the rods, idea was to use these instead of factory LY rods and it is what it is now. I was curious what these rods look like in person given price and weight at 800 grams which is around 50 less than LY rods, also they take .990 pin…
Plan for this engine was to get decent set of parts for decent money and get decent power in return. Nothing fancy.
I used to drill and bush factory rods with full balancing etc and they worked with .990 pin no problem at over 600hp range but I always felt it’s a risk given their age. I think 440 source rods are no better than these speedmasters, they look identical but have better bolts and obviously better quality control. Cores look the same.
For sure Scat or Molnar rods are in different league overall but they are more than twice the price and are heavier. We have to rethink this part… I am curious what speedmaster will do looking at photos I posted here.
