you are right it doesnt' apply to this site. THis site doesnt' talk about tractor motors.

Go here:

http://www.popularhotrodding.com/enginemasters/articles/cadillac/0505em_cadillac/

then here:

http://www.chrfab.com/

try this too:

http://www.hotrod.com/techarticles/engine/113_0303_north/index.html

four pages there.

If that doesn't do it, go here:

http://www.google.com/

and type in "Cadillac Northstar Performance"

The N* has nothing in common with the V660. The closest these things are related is in the bellhousing bolt pattern, and even that isn't quite the same.

ok then was wondering what kind of power a 3.1 mpfi with some forged pistons and a m112 blower and intercooler off a f150 lightning would make pushing 10 to 16 psi?

[SappySE107]

Probably a mess. F150 is a V8, 3.1 is a much smaller V6. You would need to know the amount of air the M112 is gonna push out and go from there. magnacharger used an M62 on a 3400, so an M90 that is off a 3800 would probably be a safer bet than a 112.

[offroader]

what kind of power would these #s make with a m90

[SHOoff]

The MP112 is an upgrade for the 3800s/c motor. So you can probably get it working if you are able to get an M90 working. But I think both of them are probably too big for the motor. Get a nice M62 if you can.

do you even have the money and the skills to do this or are you a dreamer?

damn man all it was was a simple question, you didn't have to be an ass about it

Some ppl just have to be jerks Its human nature. To answer your question Ive worked for the last 5 years as a Sub contracted Quality Control expert checking and helping design everything from Allison Transmissions to Cummins deisel engines and worked for just about every auto manufacturer in North america when they have a problem they call me! so I guess I have a little experience and could maybe pull off bolting a blower to a n/a engine....

I like looking at this thread just to see that comment.
