does the GM LS7 intake fit the ETP C5R heads? or the GM C5R heads?

thanks.

 

The GM C5R heads have the incorect bolt hole placement so the intake won't bolt up. However, I'd bet that if the LS7 intake port size was sufficent, ETP could set the C5R style head to accept the factory bolt pattern. Benefits of having a blank casting to start from!

 

thanks for info. i feel the C5R heads are better than LS7 heads, am i correct in that?


aren't the LS7 heads a 12* heads where the C5R heads are 11* heads?

I remember Cary saying that he could cut the LS7 bolt pattern to a C5r head. You would have to have the ETP casting for this.

 

we do machine the ls7 bolt pattern in our c5r as a standard unless requested otherwise.

 

thanks for the info. is there more chamber volume options for the et C5R heads other than the 58cc chambers? i mean like if i wanted 72cc chambers?

 

Yes they are avalible in a larger chamber. the upper 60's are achievable
