Owner Mike Coughlin was fully in charge of picking the powerplant and the transmission, and “he wanted to go real fast,” Sondles says. When Coughlin was a kid, nothing was cooler than a big-block, but now that Chevrolet Performance produces a 454ci LSX long-block, he could have the best of both worlds. The 620hp Gen IV has been finished out with a FAST LSX-R intake, 102mm throttle body, and a Holley Dominator EFI system. Note the engine setback and all-new firewall/cowl area.
