We here at LSXMag are a huge proponent of LS swapped cars. Who would’ve guessed? When it comes right down to it, the more unique the car, the better. When we heard about Chris Jost’s LSX-swapped G-body Monte Carlo, we couldn’t help but take a second look, and boy are we glad we did!
Chris originally bought the car at the young age of 15; he drove it throughout high school and college. Even though the 305 that it came equipped with was only good for 14s at the dragstrip, it did what it was meant to do and got him back and forth as a daily driver.
It took some time, but the mod bug eventually bit Chris pretty hard. He decided to go with a crate LT1 as a replacement motor. He even picked up some goodies such as a cam, aftermarket valve train, ported LT4 intake, BBK throttle body, and ported Edelbrock Performer aluminum heads. However, one thing led to another and Chris had no time to finish the car, so it sat in storage for four years.
After a long hiatus, Chris’s brother couldn’t watch the Monte sit idle any longer. Although the LT1 never got to see any use, it was now a bit dated by new plans for the car. In its place, a 6.0L LQ4 was plopped into the generously-sized engine bay. A couple of key bolt-ons, including an LS6 intake, 317 heads featuring Patriot dual valve springs, and a cam (of course) were at the heart of the build. To go along with the main components were some 28 lb injectors and a Walbro 340 fuel pump complete the fuel system.

With all of this work, a stock drive train would be pretty obsolete; new parts were in order. A shift kit and 3400 stall converter helped to quicken the new 4L80E trans that was now in place. A 3-inch steel drive shaft was added to get the power to the rear wheels through a 8.5-inch 10 bolt pulled from a Grand National, complete with Posi-Traction. After a few suspension upgrades and a 175 wet shot of nitrous, the Monte was able to pull an 11.59-second elapsed time at 115 MPH on some Mickey Thompson ET Street 275s. After such a long journey, it seems to us that Chris’s Monte is as finished as it has ever been.
