crankshaft front snout lenght

in a race application when and why do you need to cut the snout length down to shorter boss length? is there a big change in strength on a good quality internally balanced forged or billet crank?

I've used both IMO not a big deal.

But if your buying a new quality crank Like a Bryant or Crower they typical come with the short snout.

since this was brought up, my Crower crank has a long snout.What is the purpose for that?

I realize that but for what, whats typically the purpose?

Some guys like stuff to fit like a factory crank, use more stock type pulleys / accessories, ect.

oh,ok thanks for info

that's why i asked the question i acquired 4.50 Crower billet with a long snout, what is the typical cost to cut down a crank snout?

Call Adney at Performance Crank, he's done a bunch of them.

A lot of big block Ford cranks these days have the snout cut to small block Ford length of 3" so, dampner selection is much more vast.

forgive the question,doesn't the snout diameter impact balancer choices more than length

The shorter snout reduces torsional load also, that's the biggest reason, as well as packaging for a Mandrel. Damper selection has very little to do with it, especially since aftermarket Dampers can be ordered with either hub, at least ATI super dampers can which is what we always run.

The sbf and bbf snouts are the same dia.

An OEM dampner for a BOSS 429 engine, (which is where the BOSS length snout designation came from), uses no spacer as the original dampner has an integral spacer as part of it which extends into the front seal area all the way to the timing gear just like small block dampners; except a Boss dampner, (and crank snout), is a bit longer than a small block dampner.

BOTH type dampners can be used with a 3" crank snout.

The Bryant "Boss" snouts are ~ 3.5".

so when using an innovators west balancer built to work with the boss length, which is it...3 or 3.5?

The I.W. #210 is plug and play on the Bryant ~ 3.5" snout......no spacer needed.
