So I'm trying decide between two ways to get to the same final result.

Build a 5.4 all motor now (low compression, blower cams), and put the blower on it end of the year

OR

Put the blower on the stock motor now, and build the 5.4 to go in at the end of the year.

Of course I know their are limits on the stock motor, and would stay within them.

The cost is about a wash either way, tune is needed either way so its really just preference.

The 5.4 would have heads/cams and the vortech would have a powerpipe at least, if not a slight pulley as well.

I'm curious which would be more fun to drive, and which would perform better from a stop and a roll both.

What would you do if forced to choose one or the other ?

 

from a dig or slow roll the 5.4, from 60-up 4.6 Vortech
i say build the 5.4 and do the Vortech later.

plus i got all the 5.4 stuff i got 4 sale if interested

 

5.4 first... you need to re-learn the car's power delivery before you slap a blower on it.
