I'm considering building up another engine to drop into my '05 C6. Any ideas where and how much a stock C6 or Z06 engine will run? If I can find a Z06 engine will that line up to my transmission I currently have? Thanks

Don't know anything about the LS7 engine, not too long ago on ebay was a LS2 engine for around $3500 with under 10k miles on it. Thats a good idea! Build up another motor and swap it out.

A LS-7 427 Runs about 15k with 525hp and a LS-2 runs about 5-6k new.A ZR-1 motor runs about 15k-26k new. The stock trans should go fine with the LS-7 but as for the others I have no clue...But why get a new motor for your 05-C6 its still new just get the heads machined, port polished,headers,and a vortech Zo6 intake. Now thats cheaper then a new engine..With all this thats at least 70hp with tons of torque......

I agree with the last post. Easier than buying a new crate LS7. Probably your best move.

That said if you want to go "nuts" on a NA engine, I would consider buying the new Warkhawk 454 engine block and building an engine w forged components. It will fit in you C5 or C6 and is a superior block to the LS7. I am installing that system in a track only car I am currently building. The engine will cost approx $16,000 and generate approx 600-650 hp with huge low end torque. See link/discussion. The block will start shipping in about 45 days.

600-650??? WOW! That really gets you thinking!

Additionally, the stock LS7 is rated at 500 hp at the engine. Most LS7's will dyno (on mustang dyno) at around 430 rwhp. With a cam, header and cyl head upgrade you can get the LS7 up to 540rwhp easily. The warhawk build I'm describing is good for another 80-100 rwhp.
