Back in99- 2000'ish the Chowchilla Speedway track Championship car for the street stock division had 14:1 forged domed pistons forged scat rods scat crank world steal heads I2.02" E1.60" Holly 4412 (500cfm).097" jets( two sizes larger to compensate for power valve delete) 600hp (estamated). We could lap 2nd place. 114 octane race fuel . MSD ignition throughout 6A box 32 degrees fixed timing.
Ran the same motor for the full season tore it down to rebuild it at the end of the season the parts that came out had better tolerances than the new parts out of their boxes running Mobil 1 full synthetic changing it every two weeks AKA two races 8 quart oil pan. 2 speed Powerglide replunbed for direct drive no torque converter had a valve that acted like a clutch by reduced line pressure to first gear and slip the clutches real finicky easy to burnout. On our first race taking the green flag we broke the weld on the drive shaft our weld on the rear help factory weld on the front is what broke was our only dnf( next shaft we did all the welding) end was a Ford 9-inch 6.83:1 gear at6800- 7200rpm ( motor was capable of being spun 9000rpm rev limiter was set for 8,000. 2weeks before Race season started we had a mishap when we broke in the Cam there was a hairline crack in the block and number 5 while we let it settle down and cool off after breaking in the cam for 30 minutes water poured into number 5 under pressure 4:1 gear reduction starter didn't even hesitate as a blew the cylinder wall out of number 5 hydrauliced. the Piston was sent off for metallurgical analysis because it's shattered like it was cast. That is the nice thing about blueprinting the motor it is easier to duplicate your results. .
Now add water injection if the track had allowed it and the compression could have been taking much higher. Throw on some aluminum heads that's two full points of compression so are 14:1 compression motor would be happy with aluminum heads at 16:1 all else being equal. The late models that came in from all around the country were running aluminum blocks aluminum heads 18:1 compression most on methanol some on race fuel chromoly chassis 1600 pound car making 800 horsepower those guys were fast. They told me at this level of competition if you're not spending $40,000 on one motor you're not expecting to finish on the lead lap most of these teams had three spare Motors and a complete TurnKey car tuned to the same as the one they were running. The big times came to a small town dirt track
