Default Block # help???

Can anyone point me in a direction here? On a 79 L82 non-matching how can you determine if it is a L82 block? The #'s on the frt below the head are V0206TYX,50137. Casting # on the drivers side rear is 897000. Is this an L82 transplant or just a plain Jane 350?

I didn't find any such casting number. Are you sure that the first number is a 8 and not a 3?? There are following casting numbers that could look similar:

3970010
3970020

I think that you have a 3970010 which could be either a 2 or a 4-bolt block. My 383 stroker is built on a 3970010 block and it's a 4-bolt

:cheers:

You are correct it is 3970010. Is there anything that the #'s on the frt of the block tells you? I guess my question is anyway to to determine 2 or 4 bolt from those #'s?

no - the only way to find out is to either take of the oil pan and check it or to drain the oil and use a bore-scope to look inside to see if it's a 4-bolt block. 3970010 is one of the most common casting numbers...

Default Found this on the casting #

"3970010....302.....69....4...Z-28 Camaro
3970010....327.....69....2...Trucks and industrial
3970010....350...69-80...2 or 4"

Does anyone know of a way to break down the V0206TYX

I believe the V=Flint Plant 0206=Feb 6 TYX=?????

Anyone????

Default For those of you interested

http://www.nastyz28.com/spmenu.html

This list all the suffixes found on the right frt pad under the head and the use of the motor originally. Which in this case is from a 1975 1/2 or 3/4 ton pickup :nonod:

here's a neat trick:

Actually you CAN tell if a block is a 4 or 2 bolt, just by opening your hood.

Look at the pad where the waterpump connects to the block on the
passenger side. If it is a narrow pad that sticks out a little over an inch,
its is a 2 bolt. If it is a wide pad that sticks out about 1/2 inch, it is a
4 bolt. No kidding. :smash: :smash: :cheers: :cool:

I agree. It the suffix starts with a "T" then it is 99.9% likely it is a truck engine.

its is a 2 bolt. If it is a wide pad that sticks out about 1/2 inch, it is a
4 bolt. No kidding. :smash: :smash: :cheers: :cool:
I have two bare blocks in my garage and they are the exact opposite to the above :rolleyes: I don't think 2 and 4 bolt can be identified without dropping the pan.
