.20 overbore 6.7 worries

[Poulina]

Spent a small fortune in getting this engine together, now I’m spooked about trying to push 900+ hp through a 4.23 bore.

I’m having nightmares about cracking a water jacket or cylinder.

Setup is in sig. Will always be a single charger truck.

How concerned should I be.

I ran that setup for about 3 years and I was nervous, but never had an issue. This was on a 24V Ppump setup.
