300X Block Sleeves

[Deano]

Does anyone know if they still manufacture 300X sleeves? I see them online, but the engine builders here would know for sure.
I'm being told that a sleeve needs to be built so it's extending my block work to months. lol

Advanced sleeve in Ohio, I don't know if they fixed the low intake ports since the last time I bitched at them. Fuck those motors anyway.
Those lost foam block were of very sporadic quality, the quality of aluminum was piss ass poor and lots of porosity issues.

As much they don't tend to relax from cool down and maintain the interference hold, so it's a good measure to pin the sleeve on top of the bore.

I'll go this round with the rebuild since the other has 2 hours on it. If she goes again it's time to upgrade. Thanks for the info
