I am build a new motor and punching it out to a 355ci. I want to know what is the stock stroke. I am using of course a 5.7 rod.
I am trying to order the crank tomorow and need the specs.


Also, what do you all think of the crank listed above, how stronge it is , weight, etc.

 

Stock stroke is 3.480" which many call 3.500".

 

slopokrodrigez you never got back to me about you calling the counter weights on the crank "bobweights" see i was just trying to inform you that you were wrong

How old are you?????? First of all stop wasting other peoples threads. If you had to inform of something trivial, then PM me. Second of all, the weights on cranks were called bob-weights long before you were born. Old habits are hard to shake. Third, get a life.

 

Which crank are you planning to use?

 

Lightweight, 3.480'' Stroke with 2 Piece Rear Seal, 5.7''/6.0'' Rod, Internal Balance, 2.100'' Rod Journal

you need a 1 piece rear main seal crank for the LT1,unless you want to run an adaptor.

 

how much for the adapter and problems with install

 

dont remember how much the adaptor is,and the biggest problem is they are prone to leaking.

better off buying a 1 pc rear seal crank

 

Thanks for the info, i am still thinking of the old school cranks

 

There was a reason for engineers to switch ALL engines after 1986 to a one piece rear seal. Can you spell LEAKS. Not to mention getting a flywheel to fit new engines with an old crank. You really need to talk to the guys at Nu-tek and then consider the 1 piece rear main seal Dragon slayer crank from Calies.
