best setup up
best setup up Ok guys here is the deal I just traded my 07 mustang for a friend of mine 2002 ss slp anniversary camaro. The only thing is the car had a bad #5 cylinder he is paying to have the motor pulled and whatever needs fixed fix. He also said he would split the price if I wanted to do other things while the motor is apart. It alredy has a mild cam in it then the car has pace setter long tube headers off road y pipe, moser rear end with 4.10 gears, lid, and suspension work already done. So what do you guys thank I should do I have about $1500 to $2000 that I could spend on the car. Should I put forged rods and pistons in it, the car already has the nx maf system, and just spray it, or should I do different heads. Pretty new to the ls1 thing so just give me some input.
Thanks

You need to buy a new short block. If this thing has n2o running through it and the #5 cyl is bad , the whole thing is toast. Forged 347 and look for some used heads if money is getting tight. You can get a new sb for 2500-3500 for a forged 347. Weber had some good specials going, LME is a solid company to go with, they've built mine and few in my area. Sponsors on the right, start calling them.
To save money look for used heads. 500-700 is all you should pay for a decent set, unless they are new used.

not for sure if the cylinder is bad or if it is just a piston or ring. The car sets for long periods at a time like 6 to 8 months. I think the gas starting going bad and he tried spraying on it. The car only has 16000 miles on it but if it does need a new block he said we would buy one.
Even if its a piston or ring, cost wise the better money is a new short block rather than repairing that one. Unless of course your doing all the work yourself and have all the tools, but even then it really doesnt make sense to only fix one cylinder. You've got it all apart basicaly and could add all new stuff very easily. Thats when the cost of a new short block is a better bet. To pay someone to fix it will run some big bucks unless you've got a real cheap garage to go to. You can get only the parts you need once you have it apart. But you wont know what you need until then. Get an estimate of the work to see the costs involved. Unless of course your going to tear the motor down yourself.
Ya I am definitly not just going to fix one cylinder I told him before the trade that I would at least what all new forged pistons in it, But everyone talks like the stock block and stock crank are pretty solid in the ls1 do you still recommend a new short block if the stock one is alright.

The stock crank is fine. Rods and pistons is what you want, you could have the cylinders cleaned up and go to a 347. It's a very popular thing to do. ITs just the costs involved thats all we're talking about. All a 347 is, is a stock block with a clean job on the cylinders basicaly. 3.905 bore instead of 3.900 I think is the exact spec. Who's doing the work? BUT what about the bearings? Are you certain they are fine? See... new 347 for 25-3500 doesnt sound that bad when you look at it all.
First you need to see what the damage is, but taking it to a shop will cost money just for the tear down and to inspect.

Verdad Gallardo The shop already has the car it is a buddy of mine. He got the motor out yesterday and was going to start the tear down soon. The guy I traded with already said he is paying for the tear down and new forged pistons and if their is anything else needing done like bearings rods whatever. I am wondering while it is apart if I should look at maybe a 383 stroker or maybe just do a good set of heads instead. The car will not see much track time maybe 2 to 3 times mainly street use.

You still need to have block work. How much is your friend charging you? You cant just add forged pistons.

I do not have to pay for any of the block work this is part of me trading my mustang for the car knowing it needed work, and the guy is paying for all the work to be done. But I was just thinking while it is apart and the guy is paying for this why not make it a little better, and split the difference of the parts with the guy.
You've got an O2 the heads werent as bad as the 98's and 99's. I would think you would pick up decent torque from 0-6000 rpms with the 383. If you added real good heads and a cam you could probably out do the oem head and 383 combo but it would be more of a top end oriented build. I'd do the 383 and then add better heads later. The short block is the base, the heads can be upgraded at any time. Get a cam as well if it isnt cammed already.
