Ive decided to build a 5.3 with 4.8 flat top pistons and 862 heads milled .030and a 3 angle valve job. Anyone know what my comression will be? Any suggestions for a cam?

Arent the pistons wrong for a 5.3 stroke? Pin location in wrong place for a longer rod or something? Interesting idea but I'd sure measure the distance from the center of the wrist pin to the top of the piston.
I can use L33 pistons then? Mark and I were thinking they were the same but good call greg. Ill have to find out.Quote:

True statement. The bore between the 4.8/5.3 is exactly identical and a longer rod is used. The pistons should fit perfectly on stock 5.3L rods.Quote:

You are definitely crazy enough. You are Rainbow money havin, snap-on black light covers usin Canadian who mods a V6. If that is not crazy, I don't know what is...
Mod a V-6? Huh? My 4.3 is going into retirement bud. Picked up a replacement.
Ok, so you admitted to everything else then... :lol:
And what is this "replacement???"
Just a basically new 5.3, nothing special
