A 270S I would like better.A 318 works very well with a 4 inch crank. Add in Edelbrock heads with a four angle valve job, Comp XE274H, an air gap, and a 750 4150 and it will keep pulling up to around 6800 rpm and still have plenty of bottom end torque. I’m sure the 11.3 1 or so compression helped out with that too, though! Just a great hot rod street engine. Unless your heads have a W prefix and are worked pretty seriously, I do agree with 3.79 inch crank for the larger bore sizes.

Don't think so .. new ATI Super Damper and it was fine on the dyno . I am just lucky all it did was take out the main bearing and not damage the precious R block. .. and replacement cost for a better crank is $900 to $1100... it happened last year and I am running my backup 367 now , probably going to fix it over the winterI‘ve seen that before and it’s not a crank failure. That’s a damper issue/failure.

Thanks for the info , I will look into it as I never thought of the balancer going bad but it could very well be as a matter of fact this motor had a previous problem ( wiped the bearings while on the dyno after the initial build ) I wonder if the problems are related ?I’d have someone look at it that understands harmonics because that’s a fracture that occurs when you have a frequency issue.
I had a war with ATI in 1989. Their dampers are tuned for a very narrow range. When you call them and tell them you have a certain bob weight and an RPM range that most don’t run, and they try and sell you a damper that is tuned for lower RPM, heavier bob weight…I have an issue with that.
Like I said, I’ve seen several cranks broken like that and a couple of them were in the first stages of failure. All of them were damper related.
Well, I never said which BRAND forged crank. LOLThe Eagle forged crank in my R3 /408 after 200 or so runs shifting at 6500
