If I put the heads and intake manifold, tb, and all of that on my block....Would it not be basically the same thing as a complete 99+ GT motor?
My block is perfectly fine, low miles and all of that.
I was just wondering b/c it's a lot cheaper to swap heads and intake than it is to swap the whole motor.
Thanks
You didnt mention what year of MN-12 you have....either way, for this example, i'm going to use a '96 4.6L (like mine).
adding PI heads/intake to a '96 4.6L would yield a higher compression ratio than that of a '99+ GT motor. So it depends on what you want to do. If you want to supercharge your car, you might want to go with a '99+ motor.
If you want to go naturally aspirated, the higher compression of a PI headed '96 4.6L is perfect for 91/92 octane pump gas.
I think that's the way it goes, if I am incorrect in anyway please rest assured that one of the senior members will post the proper answers, correcting my mistakes.
check out the engine tech articles for more information on how to install PI heads if you choose to go that route.
