I guess it would be a good test to take a 5.0 out of a junkyard F150 and try to Sloppy turbo it. See what happens. Maybe the internet can convince Matt to give it a try.

Random Fairmont article: http://www.dragzine.com/features/car-fe ... t-sleeper/

Never really gets old.
Happel discovered a 1999 4.8L GM motor through a friend that runs a salvage yard, equipped with paper head gaskets, and paired it up with a 76mm turbocharger and a 4L80E transmission out of a 2000 Silverado pickup for the new project. 80 lb. injectors were added to the combination, along with an LS1 intake to allow the engine to fit under the hood. He and his friends also swapped out the 7.5-inch rear end housing with an 8.8 for a little more strength out back, and added a set of slick (that he bought for a whopping $26) and mounted them on the stock 10-hole wheels.

Initially, Happel ran the car on the stock camshaft, and the first time he had it out at the race track, carded an 11.0-second lap at 126 MPH. “We wanted to see what it would do with the stock cam, and then throw a turbo-specific cam in it to see how much it would pick up,” says Happel.

Happel picked up an ISKY Triple 12 camshaft and proceeded to pick up a full 10 miles per hour in the quarter mile — 136 MPH with an elapsed time of 10.72 and a 1.81 short time — without changing anything else.

“So many people spend too much time trying to make everything look too nice and they never get the car done and they lose interest. People also think it’s outrageously expensive to make a junkyard engine go fast. If you read around on forums, everyone’s so quick to suggest that you replace everything in a junkyard LS engine. It kind of makes me angry — why would you tell someone to buy a junkyard motor and spend two grand replacing everything in it. Where’s the cost-effectiveness in that?

“I give all of my information away, even tunes I have on the vehicles, and I just show people that you don’t need a million dollars or to get frustrated all the time to go fast. I love telling people I only spent so much money, I drive to the track, that it’s reliable, and it goes extremely fast.”

And in case you were wondering the total investment in the Fairmont to go 9.68…Happel estimates around $5,000, lock, stock, and barrel.
Yup.

They came back with a dimensions and weight comparison except I don't know where the LS3 went.

Anyway, the LS (now supercharged) and SBC win.
