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 |

Stick with your niche, if you need to expand cover the rubber/plastic (etc) parts for 356 and 911, venture into other cars, etc. |

I was just looking for them a while ago, needing a new or rebuilt engine. I found Raby, too expensive for me. I found some builders that went out of business. I found some builders scattered around the country but not convenient for shipping and expensive. I found a race shop several hours west of me, very expensive. I found one local builder that does a lot of VW stuff, he is booked out 6 to 9 months. And that has been the end of my work. I am sure I have missed some. But from my perspective I would say go for it! |

(IMG:style_emoticons/default/agree.gif) Everyone claims there’s tons of people who can take these jobs on until you look for them and everyone is too busy, too expensive, or ready to retire. The cars aren’t going away but the people who help keep them on the road on the business side seem to be |
