500 efi vs 525efi
Is there a difference from the 500efi cam to the 525 efi cam?
If so does anyone have the cam specs of each. I currently have the 500efi cams and rebuilding the motors looking to replace the cams. Also they are blower motors. Thanks |
The 500 efi uses a Crane 169621 hyd roller cam. The 525 efi uses a Crane grind that is very simular to the 168741. The differance is that the 525 cam is ground of 114* vs the 168741 on 112*.
Cam cards for both can be downloaded from www.cranecams.com using the above part #s. |
Gettinbye thanks for the information.
Do you think it's worth it to jump to the 525 cam in a blower efi set up. 525 cam looks to have more duration. |

Would not hurt at all. The "741" cam has been used extensively in both naturally aspirated and blower applications. The stock 621 is also a decent grind. Like most anything else guess it depends on how much you want to spend! Do a search here on OSO and enjoy the read. Lots of info on here.
