Anyone know or have any 5.0 pistons that are better than stock. All I can find under $350 have a lower pin height. Even if I spend more I'm not seeing many options. I'd like to be around 10-1. Using either D0 windsor heads or gt40s, I have both.

Are the stock TRW forged pistons not good enough. It looks like Sealed Power makes forged replacements of these. Both standard bore and .040 over

The last pistons I bough I had custom made by Icon. Can't remember the cost (they came with a stroker kit I ordered). LOADS of options.

BTW the stock pistons IIRC are hyperneutecnic, not forged. Could be wrong. I'd be more worried about the rods.

Now that you mentioned it, I think the did switch! I have the official 5.0 manual, but it must be at the shop. I'm almost positive my '88 had hyperyouwreckedit. Anyways, I'd still be more worried about the rods.

meh... I have put 4 cars deep into the 8s this year, all with stock bottom ends with hyper pistons.. on 20+ lbs of boost.. hyper pistons are great until the tuneup cannot handle them. detonation is what kills a hyper piston. If it were a low boost or NA application i would always choose a hyper piston over a forged for longevity.
