"Billet caps necessary when using girdle?" or instead,
"Girdle necessary when using steel caps?"
![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
I have heard 3 different opinions from "Buick experts".
1. Girdle only
2. Steel caps only
3. Both
4. Pour hard block up to the water ports [My opinion!]
None of these items remedy a very weak point in a production block - the thin main webs.
Have seen broken block with both.
Have heard of broken caps with a girdle.
Have seen damage with caps.
My personal opinion, in the 10's first choice of parts would be a forged crank. Faster than that, go with a better block!
