And is there any problems just cruising an aluminum block on the street?



and just because a handfull of people did it does not mean it is reliable.




Why isn't it reliable? Please, do tell? CHIP


my point was about the pressed in sleeves possably leaking if nothing else over time.



Aluminum blocks are every bit as reliable as iron. All the GM LS1, LS2, LS6 and LS7 blocks are aluminum. Many of the import high perf blocks are aluminum as well. I have an aluminum block on my Cobra replica-4 years and running with zero problems. The NHRA pro stock guys use compacted graphite blocks but the IHRA guys all use aluminum for their mountain motors.


you did not name 1 mopar block[aluminum aftermarket].i am not trying to argue but learn from this post.
