Crankshaft snout

Thinking about having my 5" snout cut down. The bolt hole is drilled 2" deep, is it necessary to drill the new hole this deep?

I'd say yes, The Factory did it for a reason.

the Question is whydo you think you have to cut your crank off? there has to be some reason for you wanting to do it?

I think it's just to long in the dragster. BBC and BBM are drilled approx 1 1/4" deep.

They also have fatter snouts I believe.

and it ant no cheby

you know there are lots of 1000+ hp engines running on here with the longer snouts... These are not Big Block Chevies or Mopars (Bandaids) so quit talking like they are... Please... Read and adsorb info...

I don't have any Boss Snouts to Measure, are the Boss ones 2" Deep? Randy?

What brand dragster and what wheelbase? I had a 225" Undercover. I had a bbf with the long snout in it + a 4" long mandrel on the front of it for the belt drive fuel pump. The bolt head at the the front of the mandrel was about 2 3/4" from the blow shield.

Dave one of my Boss Cranks the bolt hole is 1.83 deep... I just checked one... but I think they should be close .....

Some of us have a radiator behind the blow shield. With a boss snout and a Ron's mandrel, my old balancer bolt head was about 1/4" away from the fan shroud. I'm hoping with the new set up, that I will have 1/2".
