Cylinder Head Vital Specs - Power Curves
317.862.0223
aeroheadracing.com One of the bargains we tested was the Aerohead small-block Chevy head, featuring a larger com-bustion chamber than most tested. It should be noted that this netted a lower compression ratio. These reconditioned Dart Iron Eagle S/S heads pro-duced a healthy torque number of 475 lb-ft at 3,900 rpm and 430 horses at 5,700 rpm. With these heads you can gain power and save money. | CATEGORY 1 | | MODEL: | Aerohead Cast Iron, 165cc | | PN: | ARO-CH-1D-SS | | PRICE: | $625/pair | | Weight: | 52 pounds each | | True measured combustion chamber volume: | 73 cc | | True measured intake and exhaust port volume: | 178 cc; 70 cc | | Spring pressure: | 90 lbs. on seat; 270 lbs. at 0.500-inch lift | | installed height: | 1.850 inch | | Valve size: | 1.94/1.50-inch | | Intake flow at 0.400 lift: | 219 cfm | | Complete, no guideplates | | Airflow | | Valve lift | .050 | .100 | .200 | .300 | .400 | .500 | .600 | | Intake Corr test flow | 29.5 | 60 | 116 | 162 | 219 | 225 | 226 | | Exhaust Corr test flow | 22.5 | 48 | 101 | 141 | 171 | 185 | 188 | | POWER | | Average torque: | 440 lb-ft | | Average horsepower: | 389 hp | | RPM | lb-ft | HP | | 3,200 | 446 | 272 | | 3,300 | 448 | 281 | | 3,400 | 454 | 294 | | 3,500 | 460 | 307 | | 3,600 | 464 | 318 | | 3,700 | 470 | 331 | | 3,800 | 475 | 343 | | 3,900 | 476 | 353 | | 4,000 | 475 | 362 | | 4,100 | 473 | 369 | | 4,200 | 472 | 377 | | 4,300 | 471 | 385 | | 4,400 | 469 | 393 | | 4,500 | 467 | 400 | | 4,600 | 461 | 404 | | 4,700 | 457 | 409 | | 4,800 | 451 | 412 | | 4,900 | 445 | 415 | | 5,000 | 442 | 420 | | 5,100 | 438 | 425 | | 5,200 | 432 | 427 | | 5,300 | 426 | 429 | | 5,400 | 420 | 432 | | 5,500 | 410 | 429 | | 5,600 | 404 | 431 | | 5,700 | 396 | 430 | | 5,800 | 388 | 428 | | 5,900 | 379 | 426 | | 6,000 | 372 | 425 | | 6,100 | 359 | 416 |
