Drifter420 is on a distinguished road

And Drifter420, the L67 is more durable because it has forged rods/pistons (8.5:1 CR) and a forged crank which is basically a no brainer on a factory */C engine. And just because it'* forged doesn't mean it going to be more reliable, actually it would be less reliable than a N/A engine.
True indeed the Centrifugal */C will definitely work better then the Roots Eaton we have.. but again... we're now going into aftermarket though.. in which case... all gloves are off in a sense. I am refering to in stock form...

As for forged pistons and all.. why would that be less reliable ?? As far as I know.. the difference is that normal pistons are a bit more giving ( more elastic in a sense ) that if for example you take a normal piston and a forged piston.. and you hit them both with a hammer.. the normal piston would warp and leave the imprint of the hammer hit.. whereas the forged ones will crack. However.. the forged pistons also has a higher heat and abuse rating. I am not trying to argue by the way... I much like most member would just like to learn more so I won't be giving people wrong ideas.

But doesn't the L67 also come with roller rockers and few other goodies that doesnt come stock with the l37'*

I was thinking of a CSC for my car but those are my plans. You are still forcing air into an engine to create boost and putting more stress on the internals. And actually the forged pistons will have less clearences than a N/A engine, and there is less chance of error on a */C engine.

As for the L67 having roller rockers, they are stamped steel rockers. And no the L67 is really not any better, you just pay for the forged internals and fuel system to support a low boost operation.

And your analogy of the hammer. Basically hyperutechnic pistons will break or shatter once they are pushed beyond their limits. A forged pistons will crack or break but can cause as much damage as well. It really depends since they are for different things, and thus used for different purposes.

But there is also the L36 has some other things the L67 does not. The L36 heads flow much better stock since they injectors are in the intake manifold rather than the heads like the L67. Really after that the only differences between the L36 and 67 is the forged internals and HD tranny and fuel system to suport the */C. That'* it, no more, no less.
