The push rod is more simple, smaller, cheeper and lighter - judge the LS series by it's specifications and durability rather than pre-concieved notions of OHC superiority - it comes out the winner.

Great article- i must admit before i had this car i was bit of a technology snob generally percieving the push rod engine as ineffeiciant and archaic, seeing as I owned and m3 and an acura. However, that article was very enlinghtening and interesting. I will be the first one to admit how wrong I was. Thanks for all the info guys. There really are very knowledgable and informative people on this forum.

In addition to what everyone else has said it really comes down to intended RPM usage range. Push Rods can easily control value events up to about 7K rpms and can be built for 10k though at this point you have 1/2 push rods. But once you are running 7K or better regularly OHC is probably the better choice.
Even though I think it would be cool to drive a vehicle that turns 10k average I'll stick with 1800 cruising down the freeway.

That miata must be a blast to drive.
There is also someone that put an LS1 in an older white 911. The car actually raised about an inch because the LS1 was lighter than the old 6 from the porsche.
