As we’ve already alluded to, Shaun is known as SS Shaun on YouTube and he’s known for demolishing opponents on the street with this car. The 370ci LS mill with fully forged internals came into the car as the result of the LS2 motor barfing up rods and punching a hole in its block during some, uh … high-speed testing on a closed course. Yeah, that’s it.
The fond memories of his ProCharged ’99 Camaro led him right back down the same path. This time though, he went for a manlier unit. This engine is boosted by a mighty D1SC ProCharger and Shaun claims that the car makes 689 hp at 6,500 rpm. Maybe it’s just us, but we’re thinking that Shaun is holding some cards close to the vest. Nearly 700 hp at the wheels is nothing to shake a stick at, but watch this car do its job on the Internet and you’ll agree that there’s some major league oomph on tap here. All of that grunt is fed through a T56 six-speed that was pulled from a late-model Pontiac GTO. We feel bad for the transmission living behind all that power and worse yet, Shaun’s right foot!
Shaun also wanted the car to be more multidimensional than his Camaro was, so instead of just bolting a bunch of drag race suspension parts under the Chevelle, he considered cornering as well. QA1 adjustable shocks live up front and there are QA1s in the rear as well. Big healthy sway bars from Addco up front and Hellwig out back are holding things level while cornering; a quick-ratio Saginaw steering box aids Shaun as he throws the Chevy into the corners, and 245/40R20 BFGs handle the turning end of things while amazingly hard-hooking Mickey Thompson 305/35R20 drag radials get things moving in a hurry.
Oh, and before you get all snooty on us and ask snarky questions about how much this car actually gets used and how streetable it is, understand that on the day of the photo shoot, Shaun drove this car 366 miles each way from his shop in Hayward to our palatial photo studio in El Segundo. It isn’t just a pretty face that can hook on the street and out-run you for a quarter-mile. This is a very well working, great looking, serious piece of iron that Shaun built with his own two hands.
If you see this Chevelle rolling around looking for someone to choose off with, treat it like you would a big, burly bouncer. Give it a wide berth, a healthy dose of respect, and no lip. Why? Failing to follow those rules may result in YouTube video of you being pummeled and thrown out onto the proverbial sidewalk!
This Chevelle is his calling card, and it is his way to throw a few haymakers like the bouncer in the corner…
