LSX376 B15 etc

As it was mentioned in another thread...may as well post up some links.

It does seem to be a solid performer.

Nice. I think we might have difficulty with bonnet height with that big boy!.

Whilst reading that, I discovered this http://www.lsxmag.com/features/sema-coverage/sema-...

I have always planned to go with a Whipple, and with the Camaro bonnet scoop, it should also fit...

Also interesting to read the first article in the series that shows the B15 Con Rods are from the LSA.

In general those crate motors are just selected OEM parts, nothing actually very fancy.

The later rods seem to be very well proven with the SBE guys who boost the crap out of engines.

Yeah was just mildly surprised they didn't go with the LS9 rods. Also reassuring that for what I want to do they should be fine for now.

You'd end up with an LS9 rotating assembly if you used the LS9 rods, as the sizes are unique in the GM product range. That would be far more expensive, putting the bargain basement LSX376 into a different price bracket. I've also read that these titanium rods aren't well suited to very high boost set-ups, which is what people wants to do with the LSX motor.

I still wonder how far the LSA pistons will go, as they're hyper-pathetic rather than forged.

Titanium rods are a waste of money really, unless for some reason you really must have the lightest components.

They serve no real performance benefit though in the real world

As for pistons, as long as the piston is a good design, too much power is rarely a cause of piston failure.

A factory forged piston will always be a good place to start. It's probably the best place to start as rods and blocks rarely break. A friend picked up a set of ls9 pistons for $100 in the summer. They're on his shelf. I wish I'd seen them first!

As for 'to much power' I agree with that statement. I've never seen a piston squashed or seized form high power levels. They'll break if the tune, fuel or spark is wrong though.
