The explorer motor is SOHC, not DOHC.

and its 239hp due to restrictive exhaust, mechanical fan, tune etc. Aviators have the DOHC 4.6 aluminum block :( so jealous of that motor!!!

PI will give you about 260

I'd guess it'd give you the 260 because you won't have the "restrictive exhaust, mechanical fan, tune etc.".

I'm guessing that if you're going to go to the trouble and expense of putting in a new motor, you might as well put in true duals, and get a good tune.

The explorer PI swap is easy and I think it is alot of bang for the buck.As long as you get the tune your golden.Even though the DOHC has more power it is also much heavier than the Alluminum PI.

NPI 4.6 vs PI 4.6 = night and day difference.

Yeah exactly.. you will be able to get the 260+ out of it.

what about with a blower on? will there still only be about 30 hp difference between the PI and the DOHC? and what about mods, does the DOHC get more power from mods?

Alright...this topic could continue forever...
The BEST way I can sum up a topic like this is:
If you had $1,000 to spend on each motor..... which would have more hp?
For $1,000 you could install used comp cams, springs, and get a tune for the SOHC..... which SHOULD yield more power than a DOHC.
If you spend $1,000 on a DOHC, you could MAYBE get a set of used cams.....and you'd still need springs and a tune...
I'm pretty sure only the LSC dohc had 290 hp...the others had 280, im pretty sure.

Oh well...Some people say that the reduced weight makes up for the less horsepower, but like I said...if you spend $1,000 on each motor, I do believe you'd net more HP with the SOHC...just because you can do the valvetrain for half price

why do people go through the trouble of doing a pi explorer motor swap instead of just a pi head swap? won't that do the same thing and be easier?

Well I guess the new Explores even have a better motor now over the Aviators, with the 3v. Someone correct me if im wrong but a 3v motor is better than the 4v's? Main reason being the VCT.

You are looking at a 20hp difference between the two motors.And for the extra cost of modding I couldn't go with the DOHC.But my goal is to have another bird and install a DOHC in the future,This way I'll have both.:D

Droping a whole complete PI motor in a bird is alot less hassle and can be some times cheaper.Beside's that you can keep compression down with doing the whole swap so that way you can force feed the motor later.;)
Eric,
Just let me know when you are going to jump on the PI band wagon and I'll be there to help you install it.
