Stock Piston Dish size

I8ACMRO · December 20th, 2009, 11:36 PM

what is the stock piston dish size on the 99-04 GT's? More specifically 2003 (if that even makes a difference.)

BakerFX4 · December 20th, 2009, 11:39 PM

NPI 52cc

PI 44cc

The heads share the same 1.752 Intake Valve but went from the 1.339 exhaust valve on the NPI head to a 1.417 on the PI heads

Pistons are interchangeable between the DOHC and SOHC, 6.8L, 5.4L & 4.6L engines.

But you will need to check piston to valve clearance when doing so.

SOHC 4.6L, 5.4L,and 6.8L

1999 thru 2000 ----- 18.10cc dish

DOHC 4.6L
1993 thru 1998 ----- 2.66cc dish
1999 thru 2002 ----- 4.54cc dish

DOHC 5.4L
1998 thru 2004 ---- Flattop

Thanks for the info. That would explain why 01-04 had the higher compression then the 99-00

Kinda bunched up but you get the idea

I8ACMRO · December 21st, 2009, 12:27 AM

One more thing having to do w/ compression ratios....How much would be too much compression? Was thinking of like a 11:1 NA setup bored 0.020 over and living in CA 91 is as high as I go.

Check Ford Racing. They don't lie.

Scott2001GT · December 21st, 2009, 12:30 AM

I guess then the 99-00 like boost a lil bit more?

Scott2001GT · December 21st, 2009, 12:30 AM

If I was all N/A I would want a 12 or 13 compression

Stock Heads are 44CC End Story.

Sean Hylands Heads might not be but stock heads are 44.

Maybe you should call FORD RACING and tell them there heads at 42 and not 44
