If you haven't already, look through this thread. This is where I bought my engine.

Why an Eagle crank and rods?

What year/model transmission and diff are you running? That is going to be the Achilles heal to making reliable power.

Molnar makes nice parts also and I've spoken to him. He said under 1500hp his parts will be fine.

Remember that if you are using the LSA piston squirters they most likely won't clear a 4" stroke unless you use Katech or similar aftermarket ones.

just what khole recommended me to use. I want a barrier of 1200whp then down the road years I’ll redo my rotating assembly for 2000hp and maybe drop every pretty penny to make this a 2000whp car. All thoughts but for now I want a 1200whp capable rotating assembly is eagle crank and rods enough?? Also doing NOS later like in 8-10 months

Is ERL in business? Thought they closed down for the performance market.

Steve at RED has a similar sleeping solution though if needed.

afer pricing yhe ls9 setup I got to wait cost more than i thought it would and I canít get rid of my heads so guess Iím staying with them. Would it be safe for 10:1 compression on this 427 with a blower cam and a stock ls7 intake and TB and drive around on that low of compression for 91 until I get money for a blower wanting atleast 800whp on the blower for 91 and meth. Would this be fine? Is the compression good for 800whp on 91?

You're referring to 2 different things.

Balancing is one, building is another, ( or installation is a 3rd if that's what you mean )

As usual, you aren't doing ANY homework. :popcorn:

Call your builder. Have them make an itemized estimate.

Hilarious reading this with the OP blocked. Had to get a new name because of how bad he was on his original one, as soon as he said who it was, blocked him, and noticed the behavior hasn't changed.

If a basic heads/cam setup couldn't stay together for a few months, no idea how he plans to keep a 900+hp build together.

LSA on a C6, it wont make 1000 but the car is fast with nitrous, we just did a 408 with a better cam and bigger crank pulley. Going to bump the nitrous to 150

Make your own call on that one. Post style is shockingly similar, as is the location, and way he is acting.
