American Speed vs LS

[740EVTORQUES]

Newbie question, how do these compare in terms of usability, reliability etc? No worries about ultimate power as they’re all fast enough but don’t want to skimp on the purchase price and end up with a lot more headaches!

Thank you.

So stay clear of American Speed is the general advice?

Thank you

In the past the Factory recommended builders to use American Speed, but don't know what their position is today though

The reason I ask is that I've found a nearly new GTR with an American Speed engine. I'm not chasing Ultima(the) power or performance, I'm sure they're all good enough, but just want that Ultima experience without too many headaches.

I'm more than happy to do the odd bit of carb balancing if that's what's required though.
