Everyone loves a good burnout, but some people definitely take the appreciation of billowing clouds of rubber smoke to a whole different level. One such smoke show enthusiast is Jamey Flannery, who built a classic Ford truck with the mission of shredding tires in style.
Having raced in the Lucas Oil Off-Road Racing Series Pro 4 with his truck, Flannery wanted to put the kind of power he utilized on the racetrack to use on the street and in various burnout competitions. To that end, he turned to the experts at ROUSH Competition Engines for a race-bred powerplant that would have no trouble achieving his goal.
“He used to race back in the day in the Chevy Thunder trucks, so he had this old truck and they did the build and he had an engine leftover from his Pro 4,” Ron Sharp, Program Manager, Competition Engines at ROUSH Competition Engines, explained. “And he’s like, I want to put a carburetor on it. And I want to be able to do burnouts. And I want to be able to enter the burnout contest. And I want to be able to drive it all over the neighborhood.”
If you aren’t familiar with the Pro 4 class, it was the top-tier class in the series’ short-course, off-road racing. It featured relatively open rules, but did mandate a spec-fuel injection system, so Flannery wanted to unleash the full potential of the combination for his burnout machine.
“The carburetor is always worth 10 to 15 horse—every time. I remember back in the Hot Street days, we’ve tried and tried and tried with the fuel injection with Robbie Blankenship, and we just couldn’t,” Sharp reflected. “We were always down 18 to 20 horse. Now, since then, they’ve come out with the different types of fuel injection systems where they’re more like a carburetor. Robbie’s car now has got the Holley system on there and the thing works perfectly. So, it’s come a long way since 2010 or whenever we did that test.”
Obviously, technology progressed immensely since the Hot Street days, but the powerplant for this tire-burning truck has its origins in the NASCAR ranks. The RY45 engine traces its origins back to the Ford FR9 engine that debuted in NASCAR back in 2014. However, while the FR9 is a cast-iron piece, the RY45 is based on an all-aluminum block meant to be paired with RY45 cylinder heads and a matching intake available from Ford Performance partners Roush Yates Engines, which is obviously closely connected with ROUSH Competition Engines.
While the major hardware comes from Roush Yates, rounding out the engine means calling on a familiar list of aftermarket stalwarts.
“You can buy all the rest of the components through, you know, Bryant crankshaft and a Daily pump and COMP sells cams now and Jesel sells all the valvetrain components, but you can buy the block, the heads, and the intake manifold all out of the Ford Performance catalog,” Sharp said.
As you see illustrated in the photos here, the team at ROUSH Competition Engines, under the direction of Sharp, created quite an aggressive powerplant for this street-driven hauler. Mike Kasch performed the engine building duties, while Ken Kopas put together the cylinder heads for the project. They all got an assist from Jeff Couch, which keeps the shop humming.
Though there might have been a reason to tame the compression and camming to make it a bit more streetable, that wasn’t the plan for this powerplant.
“It ended up making like 930 horsepower (in Pro 4 trim), I believe. He said, ‘No, I want exactly what I have that way. When I do a burnout in front of somebody’s house or even at a party, I can tell him, I just did a burnout with my Pro 4 motor,’” Sharp recalled of the truck owner’s goals.
One thing’s for sure, it won’t be short on horsepower when Flannery fires up his F-100 and lights up the tires. There is no doubt you are in for a heck of a smokey celebration, so tell the neighbors if they want one of their own, ROUSH Competition engines can supply the motivation.
“This truck is a killer combination,” Dennis Corn of ROUSH Competition Engines added. “Not exactly practical, yet, quite satisfying!”
