Russ Coffell (Owner) of Diabolical Racing from Flint, MI. Credentials include 20 years NHRA and dominating the Flint street racing since the late 80's. If you or someone you know has raced in Flint, you know how the story ends. AKA "The Hitman" because if your car lines up against me, it gets blown away. Worked decades as pro engine assembler and tuner. Placed 17th in Popular Hot Rodding First $100K "Engine Masters" 2002 .
Graduated honors U of M (Ann Arbor) Bachelor's Degree 1994. Worked for GM (GMPP/GMM) in 1995. Immediatey recognized the flow and performance potential of the OEM Vortec (L31) cylinder heads and released them accordingly for SPO (1996) with other performance parts and base engine assemblies (including 260HP base 350).
GMPP/GMM Chief Technical Specialist.
1998 promoted to GMPT Chief TD Coordinator all SBC/BBC (GEN 1, GEN3, Race Programs). Worked at GMPT HQ, implementing suggestions to save GM money (including substituting E85 for race fuel in the dynos), refined production processes, while proving cases against inferior production suppliers . In 2005 after Recardo (GM's engineering source in 2004 for the LS7 ) grenaded over 90 hand built 7.0Ls attempting to make 505HP @ 7000rpm, I was assigned to root caused the issue. At this time I informed management there was a design flaw in the piston compression height, wrist pin, and circlip design. After management refused to listen, I took things into my own hands. With the help from my collegues in the UAW (Metal Model Makers), I had crude but functional AL intake fabricated that coupled a LS engine with a V6 supercharger. Using a 1 hour used 6.0L LS2 engine (DFS Designmated for scrap) with cast pistons, PM rods and "993" rectangular port heads, fabbed intake, and EOT 3800 V6 SC the "unofficial" prototype SC 6.0L LS engine made over 700HP mandating managements attention while not making many friends. This prototype haulted the production of the hand built 2005 7.0L LS7 overnight and was used as the proto design for the LS9 (6.2L) 638HP SC engine. The LS9 was the most powerful SBC in GM's history and remained in production thru 2019. While at GM i built or designed engines coast to coast from Petty Driving Experience to Frank Hawley Drag Racing School. While at Petty I drove NASCARs on Charlotte Motorsport Raceway and with Frank Hawley in Ponoma, CA. earned my NHRA Super Comp License going 8.19 , 8.21, 8.29 @163mph resepctively.
After working at GM for over a decade without receiving the compensation I respectively thought I deserveded, I left GM and opened Westside Engines in Flint, MI where I started providing custom SBC engines and Vortec beehive valve springs worldwide. Westside Engines was in Pontiac High Performance magazine (Westside Engines OEM head 12.5:1 GEN1) Wins GT-1 class championship outing GM's Factory LS team using a GEN 1 Vortec head SBC 355 all season (Waterford Hills, MI).
I provide performance SBC crate engines, load matched SCCS beehive "drop in" valve spring packages for the Vortec heads (up to .550" lift), and dyno proven "Hitman" 65K HEI ignitions. I take pride in making big power with SBC engines while providing OEM quality components . Please visit the products pages for details why my valvepsrings and ignitions are the choice of many winners.
