crank pilot delemma

as long as it has been checked out and made sure it is right run the crap out of it..... Most of the problems with them are the bigger cranks the bore hole in the rod throws are ...... hmmmm thin from the inside to the bearing surface.... and have them checked to make sure the journals are round. I see no problem with the rods. I would run it if you have it allready together....
We were just trying to save you time and money cuz the Stock Crank is major strong.... I have a stock Crank stroked to 4" and been turning it 7400 for years and not a single problem, looks like new last time I saw it.....

You guys are probably getting tired of my endless pit of questions. But, did you mean run the crap out of the stock or eagle crank if it checks out okay? And how do you stoke a stock crank? Never heard of that.

You offset grind the rod journals to BB Chevy dimensions. Been done for years and it works. We ran a 4.150" offset ground stock crank for several years, with zero issues. Used to be the cheap way to get more displacement before the aftermarket cranks became available.

Wouldn't that make the journals really small and weak? Wait, I get it now, but I question how strong they would be. But they can't be too weak if your turning 7200 rpm's.

Not really. The rod journals are at 2.500" stock and by offset grinding can go to 2.200" with plenty of beef left. We were making 950 hp out of our A460 headed 514" combo, no issues as I said. This is why we are all stressing the stock crank, it's a great piece with a lot of potential.

Well I just want to step back and take the time to thank everyone who has contributed to this thread. Thank you, it means a lot to me that you take the time to help me out.
