Does anyone know how well something like the Indy Maxx aluminum water blocks would hold up for street use? They are about $4400 bucks and 90-100 lbs lighter than a cast iron B block. I'm going to build a 470 or 512 stroker motor for this car anyway and I like the reduced weight on the front end. I'm just not sure how well this would hold up.

It would go in my 70 Roadrunner. Any ideas or comments are welcome.


They work great, I have a couple customers that use them on the street and drive them regularly.
