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. |

Thanks all,
This was the kind of feedback O was looking for. Definitely a few things to think on. We were looking at makung the biral cylinders here and had an idea for a twist on them that could improve cooling. I get that voids would be an issue. My idea was to utilize a process that we could replicate, and if the results were consistent, we would only have to to QC on a few in each batch. The 78mm crank is a good point. I think we can develop a pretty solid motor. The testing will be the most fun. Mark |
