The IROC case has 83mm stud spacing vs 86mm spacing in the 74 version racing engine.

Hello Steve,

The 74' RS and 74' RSR used the same Aluminum crankcase. The IROC I believed used the same case but I'm not 100% sure.

Here you see the engine of an IROC 911 with the High-Butterfly MFI and the later BOSCH racing twin-plug distributorhttp://www.pbase.com/slidevalve911rsr/image/54215033

To provide you a definite answer, I'll have to research my books which are packet away at this moment. Sorry I can't be of more help to you at this time.

How does the IROC case differ from RSR
