Did they raise the compression ratio in the 2000 4.6 from the 96 4.6 (2v) enough so that I would not be able to use my 10lb vortech blower on the new engine?

Ask questions if you have'em, anyone who thinks they're too cool, know's it all, or doesn't want to look stupid has more problems than you.

Yes, the 96-96 4.6L SOHC engines have lower compression ratios then the 99+ SOHC engines. The simplest reason is becuase of the PI heads.

as for 10lb's of boost, you might have to lower it down just a little bit, to 8-9, some will say you are completly fine, others will say lower it to 6lb's of boost. I think you will be fine as long as u have the fuel to support them.

Actually the compression is the same because simultaneously they switched to dished pistons (technically 96-98 pistons were also dished but with smaller dish). But if you bolt PI heads on 96-98 block you'll get higher compression (10.5:1 area), perhaps this fact created some confusion.

Didn't they also raise compression in '00 or '01 on the SOHC motors compared to the '99's? If so- anyone know from what to what did they raise it from?
