Ending the season early with a broken crankshaft

Like all things there’s a trade off. I Have considered doing this many times but always decided against it. I really don’t want the extra rod angle with the shorter rod. We have spoke about pulling it off with the 6.760 rod opposed go the 6.535 rod. My pistons are custom built so we would have to have another custom set built with shorten compression height to pull that off. Still don’t think we will play that game because it was a very happy 528 til this happened. Car seemed happy too with this setup.

I’ve considered goin to 540 so many times just like I’ve considered glide, alky, etc. still racks my brain daily hahah

Couple of my friends have a 604" 9.8" deck BBC, the rods in that are 6.385". It made 1320HP on one carb. I may have misread your posts but it appears you need pistons rods and a crank? Or were you just going to buy the odd number of pistons and rods you'd need, reusing what's good of the old stuff? I have good respect for your engine builder and I'm not sure if this goes against the grain of what he's advising or is it from you? I know you can get some if not all 4.25" cranks to balance after you cut the counterweights for a 6.535 rod on a typical 1.3 c/h piston WITHOUT adding mallory. Now if you had a stock block, I like the longer rod for the reason you stated.
