Hey all,
I'm new to the forum here. I was searching the internet for an answer to a particular question of mine but could not find one for my specific scenario. I'm looking at the LS and Hemi architectures and trying to figure out which can hold the most power? I'm not trying to start a brand loyalty war here, nor am I looking for which is the best overall engine option for me. I've asked a couple other forums like LS1Tech as well about this. I want to leave aside aftermarket support, budget limitations, tunability, etc. I'm simply curious as to which is "built beefier", so to speak. I know that LS and Hemi are especially neck-to-neck in power output, but which is, especially concerning the block, stronger and capable of taking more stress? Thanks.

 

Your rite.... Lots of variables....
This is only my take: Only answering the first question.... The LS has more usable resources to make the power with a Stock OEM non-Performance engine block and have it hold together....
Just my 2 cents.

 

Thx. Do you know about any differences in strength between an aluminum block LS and its cast iron equivalent?

 

I think its more weight advantage. Just my opinion
