ok if i get a decent cam, one thats streetable but offers great gains, and i get a good set of heads, i will also use chromeoly pushrods, now does anyone suggest i should get forged pistons and rings? what else is recommended to get rid of the piston slap and make my motor string so it doesnt blow up with the ported heads and cam will the stock crank be ok for roughly 400-430 rwhp? will the stock rear hold up to this? thanks guys

for a boosted/nitrous car..forged bottom end wouldnt hurt. but the stock block will also be ok for your 400-430 provided the tuning is good.

no problem...double that..and u might have a problem

depends...it should with just 400-430 but you never know. more than likely it will for awhile.

thanks for the quick reply if i had a decent cam would that take care of me hearing the slight piston slap? or would that also get louder?

If you just want to drown out the piston slap noise, turn up the stereo.

lol, i do that already, im just tired of people asking me if i have a lifter tapping and others who know what they are talking about ask me why the pistons are slapping

If it is so obvious, you should take it to your dealership and have them repair it.

If it's out of warranty anyway, I'd experiment with thicker oil...speaking of which, what are you running currently? And what filter?

Mine got super-quiet with Mobil-1 5W-40, their "Delvac-1" label. They now sell a Mobil-1 5W-40 labeled "Truck and SUV".

mine isnt out of warranty, when i bought it 3 months ago they made me purchase an extended warranty of 60,000 miles, it has 32,000 right now, and i did take it to the dealer and they say nothing is wrong and its normal.

Convienient. Sounds to me like they just don't want to deal w/ it. IMO.

bluecmaro96 what other mods do you have. Headers. TB, Stall, what else. Is your car an M6 or A4 this will play into how long your rear end will live.

gmmg exhaust, jethot longtubes, slp lid , ssra, im getting a stall and 3.73 soon, i will have heads/cam by next summer

Common? Yes. Normal? No. If there was nothing wrong, there would be no piston slap. Take it to a different dealer.

what could they do? i mean if they replace the engine ill just have a new engine with piston slap instead of a 32000 mile one right? what can they do to fix this problem?

monodax

Some have said they have gotten newer LS6 blocks when they found a good service manager that really wanted to fix the problem and not just re-ring it.
