I am interested in running a survey as to those running manley cranks and having issues with cracking. Specifically 2.3 stroker cranks, but interested in all strokes. I have been seeings a few pop up. I am nearing block assembly and I want to be certain before putting it in the block.

Manely in general has been manufacturing from china for a while, quality control will not be as high as a USA made part, this goes for the billet pieces aswell.

100mm cranks are know to crack, atleast the aftermarket ones.

I've heard of a 88mm manely billet crack aswell.

I've personally ran the 100mm billet in my car without issues. either stick with Oem 88mm, eagle 94mm and go with a 2.0 or just use a good OEM 100mm.

The best option is the 2.2, you get a very good rod/stroke ratio and can rev it up to 9-9.5k with supporting valvetrain and you also get the increase displacement.

if you are already assembling, yes the manely 100m cranks like are said are known to crack.

Thanks for the reply. I was leaning towards a 2.2 Everything is still boxed up. I do have a 2.4 block that is good.

Here's the Manley out of Ronnie's (RS Motors) built engine, actually I think it was the second one to fail.
We loaned him our spare engine so he,Brandon,and Andy could finish up The One Lap of America competition.

Why dont you do a 2.0 long rod and use a factory crank.

There's been PLENTY of cracked Manley cranks. Most builders won't even touch them anymore.

Manley is prone to cranking, stay away. Only reason the turbo tuff rods are "good" is they weigh a ton, all the extra material makes them last.


If you want a good setup, Eagle cranks do very well. I would go with stock or 94mm stroke.

Well I will report back if I find another kit to go with.

Ok, maybe they changed it up, but I've been using my 94mm billet crank since 2014 with no issues. Just passed 30K+ miles.

Stay away from Manley Forged. Billet is debatable.

So who needs a 100mm stroke forged crank? Lol
manley says this crank usually let's go after 500hp and twin disk.

I broke at 430whp and an ACT XTSS
