Why the huge price difference between LS9 and LT4?
I'm just wondering what the deal is on this?
The LT4 is 650/650 and runs you $15,625 (MSRP) from GMPP and the LS9 is 638/600 and is $25.5k (MSRP).
What did GM do to drop the cost of the engine nearly $10k?

Maybe they are just making more of them and can spread out the cost? My sense is the Z06 / CTS-V build numbers are far greater than the ZR1's were...

forged titanium rods, forged pistons, forged crank, extra strength webbing in the block other LS engines didn't have, different heads, probably some other stuff I'm forgetting. It adds up.
LS9 was "overbuilt" and is one tough mill.

It's a pretty smokin' deal...with a 3/36 warranty to boot!
A guy on LS1Tech said he had one dropped in his driveway for $12,500

I would guess it would come with the HP fuel pump. The lifter can be anything.

They both have forged internals with the exception of the lack of titanium rods as in the LS9. The price difference between the two isn’t justified imho. I feel the low production #s drive the cost whereas the LT4 is a little more avail.

Last time I looked, you could buy an LT5 for about $19K. Of course the controls pack and front end accessories were not included . Add another $2-3K for that stuff.
