IN THE EARLY DAYS OF HOT RODDING THE FORD AND MERCURY FLATHEAD ENGINES, THE EXPERT ENGINEERING AND PRECISION MACHINE WORK BY THIS AMAZING CAM GRINDER PRODUCED THE MOST AGGRESSIVE, NASTY, AND HOSTILE GRINDS OF THE DAY. STILL TODAY FLATHEAD FREAKS SPEND LONG HOURS IN OLD JUNK YARDS AND SWAP MEETS JUST TO FIND THE REMNANTS OF A OLD GRIND IN HOPES OF RECAPTURING THAT NOSTALGIC FLAVOR AND ONCE AGAIN HEAR THAT ERATic and syncopated TRADEMARK BIG LOPE OF THE POTVIN FLATHEAD CAM.

SUPER 3/4 POTVIN… A 3/4 RACE STREET CAM WITH A VERY STRONG BOTTOM END AND A HARD DRIVING MID RANGE. THIS IS A SPLIT OVELAP GRIND WITH A LARGE 357 LIFT AND A DURATION OF 270, THIS CAM HAS A KEEN SOUNDING RUMBLE AT IDLE…
SUPER 3/8 POTVIN… THIS IS A SPLIT OVERLAP FULL RACE STREET GRIND AND, MY FAVORITE,, ITS GOT A SUPER STRONG FULL RANGE AND SOUNDS LIKE IT JUST MIGHT BE “COMING OUT “AT IDLE… THE LIFT IS A STOUT 375 WITH A DURATION OF 280 “THIS CAM IS THE BIG BOY ON THE STREET”…
425 ELIMINATOR… WHEN ASKED IN THE OLD DAYS WHY HE CALLED IT THE ELIMINATOR CHUCK WOULD SAY, “SON, IT’LL EITHER ELIMINATE THE COMPETITION OR IT’LL ELIMINATE YOUR ENGINE”. THE 425 POTVIN IS A NO “BULL SHIT” FLATHEAD COMPETITION CAM WITH A LIFT OF 425 AND A 280 DEGREE DURATION WITH A REPUTATION OF BEING THE BEST FLATHEAD RACING CAMSHAFT EVER GROUND.. THESE ARE THE GRINDS WE RAN ON 95% NITRO IN THE “FLATHEAD JACK “TWIN ENGINE FUEL DRAGSTER… (I KNOW WHAT YOUR THINKING) AND YES, SOME GUYS EVEN LIKE TO RUN THIS BAD BOY ON THE STREET.
