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.
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.
Ford Motorsports clearanced all of the replacement pistons for the their old 340 hp .040 over 2 eyebrow Mahle forged pistons and rings . I bought a set from a Ford dealer in Daytona Beach, fl. I paid $ 140.00 for the set. 2 years ago. They are around ,you just have to check with the Ford Motorsports dealers to see if they still have any left.
They are 10.5 to 1 with a 60cc head and a zero deck height block. I just sold a set with Scat rods for 200 bucks. Had 4 1/8 th mile passes.
