292 INTAKE SHOOTOUT-FAIL!

DYNO RESULTS!! STOCK v CLIFFORD v OFFY v PES! WHICH ONE MAKES THE MOST POWER? WHICH ONE MAKES THE MOST TORQUE? WHICH ONE REQUIRES THAT THE MOTOR BE RUNNING PROPERLY TO TEST? HOW MANY OF US TAKE SHORT CUTS? HOW MANY TIMES DOES THAT COME BACK TO BIT YOU? DOES WORKING ON A MOTOR EVER GO PERFECT?

[@LD9user]

Does it ever go perfect? Yes, always. I've never: Busted my knuckles Been burned by touching something hot. Stripped a bolt. Cross threaded a nut. Cross threaded a bolt. Got the wrong part(s). Got the wrong parts again. Lost tools. Broke tools. Bought the wrong tool. Burrowed the wrong tool. Made the wrong tool work anyway. Performed a basic repair only to find out something mysteriously went wrong with a completely unrelated part. Had to redo a basic job (mostly brakes). Spilled any one of about 2 dozen fluids. Broke drill bits. Broke taps. Broke a drill bit drilling out a broken tap. Got dirt in my eyes. Got rust in my eyes. Got any number of over a dozen fluids in my eyes. Got metal in my eyes. Flashed my eyes with a welder. Never once. ;)

I love to see you simply put an HEI distributor on this motor then redo the tests. When I switched to an HEI it seemed like it made a bigger difference than doing the intake and adding a 4 barrel. Of course the intake and carb will support all the other upgrades, but in stock form, the better ignition was a huge upgrade. I’m currently building a 292 and can’t wait to see how this series turns out.

[@GlennEverittMasterofMachines]

I can't wait to see these intake combos compared on the modified engine - compression, cam and head, but having said that, it's been great to see how they all work on the stocker, as it'd be rare to see someone take such a path, particularly with the 'wilder' 4bbl variants. Loving this!!!

I'm an amc 258 guy so I'm loving this series of test you're doing. I do think you need to get real with cam changes and a head mill to get at least 9.5 compression. Also on the last test you turned the carburetor. I've had issues with the vacuum signal being stronger on the inboard primary. I personally run a offenhauser intake, Holley 600, voodoo cam and Rhoads lifters with 10.2 compression. Don't know about horsepower but my 3200 pound rambler runs 13.9 with 3.54 gears. Please follow through with all the 292 testing. You are doing testing we could never afford to.

[@Jeffsa12]

Ballast resistor is needed..... I believe the old GM with points ignition vehicles used a resistor (either ballast or resistor wire) to reduce the "electrical load" seen by the points. They "started" with the full 12+ volts going to the coil via a bypass circuit originating at the starter solenoid. Once running, they ran through the ballast resistor, reducing the voltage to the positive side of the coil. Full 12 volts full time = very reduced points life. Why do I know such useless info? I started hot rodding back in the "dual point ignition in my 370hp LT-1" era. Looking forward to that old 292 making ~ 500 lbs ft and at least 370hp @ below 5000rpm with some old school dual carb boost. Now let us all bow our heads and pray for really low run temps, good race gas, strength for the worn out ring lands in those ancient cast pistons, and strength for the weak ass, 6.760 inch long, SBC looking con-rods in that 6 lunged dinosaurs.

[@thecollectoronthecorner7061]

I think a HEI is needed. The spark plugs we get now are resistor plugs. and points ignition simply doesnt have enough poop in its pants to fire a resistor type spark plug at high RPM. The increased air flow is blowing the spark out like the wind blows the flame on a candle out. Ive ran a Offy 4 bbl intake with hedders and a HEI on a 250 engine in a 66 GMC pickup. It was great except for the lack of exhaust heat on the intake in colder weather. I got carb icing.

[@fascistpedant758]

You probably aren't running it long enough to burn the points, but, IIRC, the original ign. wire from the switch to the coil had enough resistance to limit peak current through the points and coil. The points don't last long with a straight feed from the battery. I once installed a ballast resistor on one of these engines used in a boat to remedy the problem. Thanks for taking all time and trouble.

[@d.collier_8280]

Yea, please don’t abandon the 292. Even tho I don’t have one, I am still interested in knowing how this engine performs. Maybe install a electronic ignition, fuel injection, more turbo stuff.

I believe Edelbrock made an SP2P Intake, only good for torque and mileage. Extremely low RPM manifold. Not worth testing IMO. The Offy always made more low end torque on all my 250 engines, the runners are small like stock Cliffords have huge runners and gives a weak signal to the carb. Three Side draft Weber DCOE’s made the most torque out of all the combos I have ever tested with different carbs and different intakes.

Since you're a Ford guy and I'm a Chevy mechanic and worked at three dealerships I will tell you something about the old points.. . You have to hit with a dwell meter a perfect 31° of dwell... To maximize the blast of a Chevy coil now I imagine that it's probably the same for just about any coil because that 31° is hyper important so when you reset the points on that thing make sure that you hit it at 31 and you'll get the best ignition of the mixture that you can possibly achieve..
