Looking to make a larger motor (4) planning on a 2665, as I don;t really want to go over 103mm to make cooling easier.
The 80 crank is available for stock rods not the Chevy rods. It is my understanding that the Chevy option offers a significant upgrade to the strength. I'm tempted to do the stock. My question is : should I wait an indeterminate time for the crank with the Chevy rod option? What am I really loosing here? or is this just a must for the larger motors? My 1st engine build. |

Well my buddy Allen who is a factory trained mechanic is going to help me assemble the motor. He was aware of the journal mod, but didn't think it was that big of a deal.
The issue is crank availability. As far as heat and thermal build up. The consensus we came to was no larger than a 103mm on the bore in this configuration. This motor will be utilizing heat dissipating and ceramic coatings, as well as some new biral cylinders we are working on. It will have lots of sensors monitoring each cylinder for EGTs and multiple head sensors. We will be running fuel injection with a new setup that we are trying to make more plug and play for larger motors. Will probably spend as much as a 6 when Im fone. But if it works as planned will be a blueprint for turnkey larger motors. |

But if it works as planned will be a blueprint for turnkey larger motors. Have you considered a possible short stroke version, for people that like that type of power. A counter balanced 1.7 or 2.0 with 103's , a well breathing induction system with the horse power a little higher on the band. |
