ok guy I know this is a f-body but I am also going to post it in pt 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

 

Up until a year ago there were none available off the shelf. I think it's Wiseco that just started producing them. You also have the option of 4.8 liter pistons or 07-up 5.3's, which both have flat tops from the factory. I'm gonna search and verify whether or not Wiseco is the correct manufacturer.
