For power, after much looking around and researching, I went with an LY6. This is the only regret I have in my build. And I say that only because of the iron block. I don't want or need the extra weight up front. I'm building this car to turn. I will NEVER drag race this car. So the added front weight won't help me at all. I will most likely swap over to an aluminum block in the future. But I'm gonna run hat I have for now. On the plus side, I am a big fan of the VVT engines. Always have been. They are obviously here to stay, so it's a technology we all need to embrace. Anyway, you know the drill. I took my relatively low mile engine apart to inspect, and I'm glad I did. Yuck, what a mess.
Here is a lousy close up pic of the engine, the day I got it to my shop. Pretty average condition.
Here's a 90k mile piston. Corn gas?
They all cleaned up nice, and measured well within spec, so I did a simple re-ring, and bearing, with all new gaskets, and ARP head bolts.
