I am trying to find some flat top forge pistons for a 5.3 trying to prove a point that this little engine run strong I am currently running a 5.3 with low compression well 9.5 and running 13.0 to 13.3 on an off but cant pick up my dynamic compression due to the dish piston. thanks for any help cant go over 8.0dcr

the currently set up is a 220 224 112+2 on a 2005 truck fullbolt on mad 345 hp on a mustang dyno and 343 tq

thanks again

you can get L33 pistons which are flat top, not forged but then you might want to look for a set of 243 heads to keep compression in the 10:1 area, milled for a little higher CR.


Everyone here knows the little 5.3 rocks

Have you checked to see what Wiseco has to offer?

Look at Mahle or Wiseco for some forged slugs for your motor. Mahle's are pretty inexpensive if you end up boring it.

Personally I'd skip the 243s on a stock bore 5.3 if all you're after in higher compression.

Chente, You don't need forged pistons for your "Frankeinstein 50 shot" that drops you 1.3 sec's and takes you to 12.1, unless you plan on running your "Frankeinstein 100 shot" JFWY.

FWIW, I beleive only weisco has a true off the shelf forged pistons for the 4.8/5.3 Bore.

Everyone else requires a custom order and the prices are almost double. How ever if they have finally steped up and do make an off the shelf piston, please do let us know.

Mr. Sandog

Bore that sucker out to 5.7 - your piston selection goes up exponentially, and no one's the wiser.
