Default Help!!

So I have a 2001 Trans AM WS6. I want to upgrade the car BUT after it is paid off completely which is in June/July.
I don't know what to do though. My engine has piston slap and I've been reading that you can't punch the aluminum block out that much. Should I go to a junk yard and get a LM7 and punch her out to a 350? Or open up my engine and see what i can do. the piston slap is bothering the crap out of me. I was reading a article about the LM7 and that baby can put out some. here is the article.

power.http://www.superchevy.com/how-to/pro...l-block-build/

hopefully that link works.

back to my story. So I was thinking get the LM7. Open her up and clean her out. Put a new cam in. Get an LS6 intake. Maybe get new heads. Any other ideas for a upgrade??

Side note I also need to convert it to 6 speed. I know this is going to be ALOT of MONEY!! I found supposably a complete kit on ebay for 2800. Most likely will be doing this over next winter. I just want to do all the upgrades at once. Oh and true dual exhaust system with headers.

Thank you in advance!!!

01-02 fbody's already have ls6 intakes, so you're good there.

What are your goals with the car and how much power are you looking to make? If you're going to want to run the best times at the track, then I'd keep your auto and stall it. If you're just street racing and it's worth swapping to you, then I'd go ahead and swap it. But a stalled auto will be hands down faster than an m6 car mod for mod at the track. Roll racing will be in favor for an m6 car though.

Is the piston slap just bothering you because you know it's there? Most people's go away after the car warms up from what I've read, but doesn't cause any problems.

I want to make about 400-450 horsepower. Really I want to put in a 454. But I don't think it will fit. So the 350 will do. And I just want stick shift. It's a personal preference of mine. I just want this thing to be a monster. That classic V8 grumble

Also with the piston slap it doesn't go away when it's warmed up. And I'm burning oil. I would like to salvage my block but I have more trust in the iron block of the LM7. Or do you think to just salavge my block? I think I just have it in my mind that the iron block is better for a beating. I did watch a video on YouTube where the guy had a 470 hp LS1.
