Finally made some pulls on the 527 Cammer

[Barry_R]

This is a "cut & paste" from my post on the FE forum - but I figured that some of you don't frequent that place...

Made 870 horsepower at 7000 RPM and 722 TQ. Absolute top line components throughout - as nice as a Cammer gets.
That's 1.65 HP per cubic inch and 1.37 TQ per cube from a vintage style package.

Billet 4.375 stroke steel crankshaft. Billet 6.700 Oliver rods. Iron 4.375 bore Genesis block. Highly modified welded and CNC ported Coon Cammer heads with raised ports that flow 456 cfm. Highly modified Dove single plane intake with sideways mounted Quick Fuel 850 carbs. Billet .705 lift cams from Comp. Prototype T&D rocker system. Compression is 11.5:1 with custom Diamond pistons, skirt coating and an .043-.043-3.0mm ring package. Crank trigger ignition with custom "T" handle MSD wires. Billet rail Moroso mid-sump oil pan. Meziere water pump.

This is the engine originally intended for the 2009 Engine Masters Challenge, and it was built to meet the rules that year. When we were unable to get it ready for the show, it went onto the back burner for a while as customer projects took precedence.

It was a challenge to get set up on the dyno - the sideways dual quads were too much tension for the old throttle actuator to pull in - it would either hang at 1500 or so if we pulled the return springs - or it would slowly release after 12 seconds or so at WOT. We were able to get clean pulls, but it sounds a bit odd coming in. Still sounds awfully good at 7000 plus!

I did make a couple EMC style pulls from 3000 to 7000 to see "what would have been". With nominal tuning it delived a "score" of 2533 - it would have been competitive for sure. Timing is at 36 locked, and jetting is at 70 square - still very safe at A/F ratios in the high 11's/low 12's. There is definitely more in there - but that's for the next owner.
