BuzzLOL . Don't need to tear into engine to determine if 1 or 2 piece rear main seal...

. earlier 2 piece seal crankshaft rear end has a counterweight cast onto it...

. 1986 & up (later in some trucks) 1 piece rear seal crankshaft is smaller at rear end and round to allow slipping into a 1 piece rubber seal and thus can have NO counterweight cast onto it...

. 1986 SBC in some vehicles is a hybrid engine with newer (possibly roller cam ready) shortblock/crank, but still earlier perimeter (2 + 2) bolt valve cover heads... (as opposed to newer 4 bolts in line valve covers/heads)

. Mexican crate engines of any year are all crappy early 1970's design... 7.6:1 actual compression ratio... (can be fixed with good pistons)

That will never happen again! after one go round with an expensive one piece, and leaking, I'll stay old school with my SBC gaskets.

My mistake, you're correct. Went brain dead, and I just put mine together about 6 weeks ago! Duh.

The block, I was told, is a gm goodwrench block. It has a suffix of vl. Can anyone help with what year this block is or what the difference in gasket sets are? Thank you.
It goes like this:

1) Pans have different heights to the timing cover Straight edge on gasket rail to bottom of arc:
1.A.) 2-1/4 thin, these will all be drivers (left) side dip stick and 2 pc RMS. will production years 1955 through 1974.
1.B) 2-3/8 thick, these are more complex;
1.B.A) 1975 through 1979 will be left side dip stick and 2 pc RMS.
1.B.B) 1980 through 1985 will be passenger (right) side dip stick and 2 pc RMS
1.B.C) 1986 through end of SBC Gen I, II production will be right side dip stick and 1 pc RMS.

If you know the month of the engine's assembly toward the change over previous year it is not uncommon for late production say 1979 to have a 1980 block and pan, so check before you buy parts if your toward the end of the production year which is the late spring to early summer before the September/October release of the new years production.

1971BB427 Most sources I've seen say that the serial number on a crate engine is just a serial number, and not an indication of when it was built, like engines that came in cars new. CE (US built) and ML (Mexico built) were used as prefixes on crate engines. I'd guess you're correct that the VL is also a crate engine designation, but can't say from where it was used. If you could look the block over, and possibly find a Mexico cast into it somewhere, that might answer where. Afraid you wont be able to answer the year without disassembling it.
Once it's torn down you can determine if it's 1955-85 or 1986 and newer by the rear main seal. If it's 2 piece it's early '85 or older, and 1 piece is 1986 or later.

1971BB427 Haven't heard of the gasket cutoff dates you're referring to before? Every set I've purchased or seen was either 1955-1986, or 1986 to end. Take a look at the Fel Pro kit. It shows applications from 1955-85.

killeratrod Chevy red-orange
Chevy orange
chevy blue
General Motors Blue
Black

The chevy red was an early color used on some of the 1950's 265 and 283's

Then the chevy orange used from late 50's to mid 70's

Around 77 they used the chevy blue on 350's and 400's, and used GM blue on the 305's

The GM blue was a lighter blue, but not as light as pont. blue. Chevy blue was a dark blue

That lasted till 1982, then everything went black.

If you want to ID the engine do not trust color. Anything can be re painted any color you want it.

Get the suffix code of the front pass side of block in front of head on machined pad..

And the casting # off the driver side rear of block, behind head on flange that trans bolts to.

vl block suffix

Hello, I too have a small bock Chevy engine that has the VL stamped on the block. Mine is VL041800. When I bought the car, it had Target Master decals on the valve covers. Problem is, the engine was built by Dr. Frankenstein. The engine was poorly painted all black. But the block was showing Chevy blue underneath, the intake was the original Chevy orange and the heads were black. The cast number on the back is illegible, so I am lost.
Have you had any luck in identifying the block, as there isn't any listing for VL in any list I have seen, and your post is the only thing on the internet I could find.

dodgeboy12008 Ok, Ill have to look. But, what if it is a 2 or 3? That wont tell me if its 72 or 82, correct?

richard stewart 3rd Hi
The "V" is a Flint engine.

Casting Date
Small block casting date is located on driver side rear of block on flange forward of bellhousing. Big block on the right side of engine above the oil pan rails.
Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec
04-24-2013 09:38 PM
dodgeboy12008 This is the hand stamped number on the pass side front, vl112832. The block casting number, 14016379, spans from 78 through the 80s so it doesnt help with the gasket kit split.
