As far as the project, I think an LS1 in a '70 is waaayyy cool. I have thought about building one for years! You have to bring it to the TA Nats when done.

Actually there is more Pontiac in the LSx motors than there is chevy, even if there is a bowtie on the block. Its easier to show what parts of the new engine are similar to chevy than what isnt. Starter, oil filter location and a press on balancer, the rest is Buick or Pontiac derived. Including number of head bolts, valley pan, passenger side cylinders being the forward set, and the cylinder heads and ports look like a symmetrical version of the RAV rather than the BBC. There is other stuff but its been a while since I compared them. To say its just a chevy is to ignore and discredit the heritage that our engines provided for the modern LSx engines.
That being said, I still wont be putting one under the hood of any of my pre 81 Pontiacs. Just isnt going to happen. This project looks interesting, and well when its all said and done its still your car. Although I would love to have whats left over from the 04 GTO, I know an L92 will fit in that thing, if it isnt bent too much.. as if I didnt have enough projects already and not near enough money for all of them...
