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. |

My 1st engine build. Seems like you're proposing a jump off the high dive, into the deep end, and planning to learning to swim once you're in the water. Forgive me if that comes off as overly negative. It is not my intent to insult you by any stretch of the imagination. You've asked a loaded question about big bore /4's which isn't an ideal build even or an experienced T4 builder. Not to mention the other aspects like rod choices, stroker crank, case modifcations, Nickies, RPM & inertia effects on the durability of a T4 crank and rods, etc. I'm sure you can do it, it's not impossible. You just need to be aware of the negative trade offs associated with the big bore route and go into it with eyes wide open. |
