Ford Crown Victoria Though they were what most people drove in the 1950s and 1960s, full-size cars like the Ford Crown Victoria are now an anomaly. But Ford's biggest sedan still offers significant virtues, including affordable V8 performance and room for six people. Today, the Crown Victoria's passenger and cargo volumes compare favorably against fashionable SUVs.

There is no difference between any 4.6 2v engine except npi and pi heads.You can put short tube headers on 2002 older vics only and bolt up .Long tubes have too be custom made to fit.2003 and newer vics have headers available from KOOKS.There are cams differences but only NPI and PI cams.

NPI is (non perforance inproved)2000 and old fullsize fords.PI (Perforance Improved) came on 1999 and new 2v engines mustang only.2001 fullsize cars and trucks got the PI heads and intakes.Put PI heads and intake on a NPI engine 50 horsepower gain but you have to use 93 octan gas .Put a PI intake with heater hose tube see 15 horse power.Also need a PI aternator bracket for the swap .

what? if it is factory, why would they need to run 93 octane? that doesnt make sense to me...

unless you are saying that because they will need a chip to adjust the computer for the new head/intake combo...

By putting PI heads with PI CAMS and intake you are bumping the compression of the NPI block to 10 1/2 from 9 1/2 causing ping (engine knock) if you use any other gas but 93 .

the only way u can get the full potential of a cai is to put a freer flowing exhaust cause it has to breath at both ends
