What will it make, 518 UPDATE - 10/27/10 04:14 AM
I'm getting ready to retest my pump gas 518 C.I. low deck stroker motor, I have tested this motor before with different heads, intakes, camshafts, crankshafts, compression ratio and different dyno brands. The last time I had it on a engine dyno was several years back, I tested it on the Studka dyno that Rodneys now runs , the motor had a set of Eddy RPM CNC ported by MCH that flowed 319 CFM at .600 on Jeffs bench, six pak intake and carbs on OR pump gas. The best pulls resulted in 718 Hp at 5800 RPMs and 744 Ft Lbs at around 4500 to 4800 RPM. I decided to change the heads to a set of Indy 40-1 CNC ported by MCH that flowed right at 370 CFM at .700 lift and a Indy 400-3 intake with a Summit two inch cloverleaf phenolic spacer. I will test four different Holley 1050 Dominators, one 9375HP, two 9375 non HP and one modified early 9375 with annular boosters Rodney was kind enough to test the 9375 annular carb. for me several weeks back so it will be interesting to see which carb. will make the most power Take a guess on HP at what RPM and torque also BTW, the 518 will go back into the Duster this winter , if it survives another test session See the last post by me on this for the updates
