|Interesting point about the LS1. It's actually the a more modern design than the GM V6 and the Renault/Pug V6 which were going to go into the car. I know it has pushrods, but that makes it far lighter than a quad cam engine. when built, it'll be a comparable weight to the V6's and more than double the power.
Anyway, I've not done a huge amount to the manta for a while. I'm still building the boot floor and the aluminum structure which holds the shell on. I'll be ordering the block, heads and bellhousing this month, and then I can start to make progress on the front of the car.
