GreenGiant2 Posted January 21, 2021 Share Posted January 21, 2021 Is the e-7 460 the same block as my e-7 in my service truck with 6 individual unit pumps. Buying a 2000 cl713 with 460 and wondering if the spare engine i have has exchangeable parts. Thanks gg2 Quote We the unwilling, Lead by the unqualified, are doing the impossible, for the ungrateful.

Vmac3 Posted January 21, 2021 Share Posted January 21, 2021 Hi Green, The block is the same but the rest of the engine components may not be. Auxiliary shaft, oil pump, turbo and injectors to name a few. They updated these components and may not be interchangeable. V Quote Link to comment Share on other sites More sharing options...
GreenGiant2 Posted January 21, 2021 Author Share Posted January 21, 2021 That's understandable. Just wondering about major thing is block. Good to hear. Heads and turbo, understandable. How about fuel. Same design for unit pumps. ? Good friend has a 460 and said he has different fuel set up Quote We the unwilling, Lead by the unqualified, are doing the impossible, for the ungrateful.

Vmac3 Posted January 21, 2021 Share Posted January 21, 2021 What year is the engine that is being sold and what year is the current engine in your truck? There are some slight changes that occurred (pre ccrs and ccrs engines). The fuel systems did change. Unit pumps are different (part# 313GC5230M) from this time frame because it was used with a new camshaft design. They are not interchangeable.

The spare i have is around a 2000 but not sure. Also it is a 315 hp maybe Quote We the unwilling, Lead by the unqualified, are doing the impossible, for the ungrateful.

Joey Mack Posted January 21, 2021 Share Posted January 21, 2021 The cam is "Degreed'ed differently. Low HP engine were retarded 3 degrees 350+400 hp were at zero degrees, 427 and up were advanced 3 degrees.. The offset cam key is painted red on one end and white on the other. Red is low power, white is Big power... The zero degree key is straight.. ..When installing the key, the color you need faces out... (front)...Jojo Quote Link to comment Share on other sites More sharing options...
