Project Discreet

Back in 2012, I bough a new Mustang. My only requirement was that it was white. Unfortunately, the 2013's were already on the lot (I didn't want a '13), so that left me with a vast array of V6/automatics to choose from.

In August of 2014, I performed major surgery on the car, and swapped out the V6/auto for a carbureted 427 Windsor and Tremec Magnum XL. It was one of five Mustangs in the world built that way, and one of only two that are driven on the street (the others were purpose-built race cars). It is, without a doubt, one of the most heavily modified street-driven S197 Mustangs in the world. In fact, the only things that are still OEM are the radiator, the fuel tank, and the rear-end housing.

This coming weekend (Jan 21), I will be embarking on what I call "Project Discreet" - adding a 671 blower with dual quad carbs to the car. Since this is the introductory post, I'll include some pics of the car during the engine swap. And FYI, the swap itself took just 28 calendar days from driving the car in, to driving the car out.

It had a monster lean tip-in condition, so I tore the carbs apart (to see what was in 'em), and bumped all the jest up two sizes. The lean tip in is gone, but now it runs kinda rich all the time. I think I'm gonna try bumping the primary air bleeds up one size and the secondaries down one size, and see what happens.

In the mean time, it runs really well.
