can a 85 318 be line bored .310 over to accept a 2.81 360 main journal?
ive looked at them many times, figured it many ways, to many! wish some body made a 3.70ish small journal crank!Here is the forged 3.58 crank with the 318 or 340 mains.

Might be cheaper just have the mains turned down on your 360 crank to the 318 340 size.
thanks,..i like that!Here it is but it needs finished. New for $200 on sale.

Molnar also has a 3.79 strokethanks,..i like that!
That would make the main webbing and the main cap bolts kind of close to each other and the main cap a little thin on top.(bottom of cap that is)

Why not just turn the crank down?
It's a circle so you'd only be cutting half of that .310 out
How much have people been hackin off 440 cranks to go in 400s? A lot. Not as much as .310, but a lot.
People only do that to the 400s when they want to go fast.
If God allows it.
I'm going to have a 360 crank cut down and put in a 318 with a 4-inch bore.
You ask why? Why would you put a 360 crank and pistons in a 318?
Because I want the markings for the 318 on the side of the block. But I want it to run better than a stock 318.

And is still done these days!^^^^^^THIS^^^^^ just turn the crank down. How do you think it was done in the 1970’s?
I like that. Cheap enough. As far as needs finishing, is that on both rod and main journals to the respected size? 331&379.
Probably.
Yea, I ain’t into that. Lol.That forging (could be a casting...I didn’t look at the link) needs every machining process done to it, including the flange and snout.
You have to find a crank grinder with the skill to do it, will do a one off one time deal and then he has to WANT to do it. Those ain’t easy to find. I looked into that and the only one I could find to do it was Marine Crankshaft, and he wasn’t all that enthusiastic about it.
His exact words were “unless you need some oddball stroke to get into a class what you want is certainly cost prohibitive”.
I think he was at 800 bucks on the low side and a grand on the high side.
