Good afternoon everyone,
I'm planning a new engine for my 6 speed g body. I have two blocks I can use, either an ls3 block that I would do forged rods and pistons with a billet 7875 or a darton sleeved ls3 that is ready to be a 427. The car is mainly a street car, I do power tour and daily it in the summer. I'm looking to one day get back into auto cross. Current setup makes 500 whp, but im looking for more. Which would you build?
