Hi pallbag, i have engine prefix VB listed as a VK engine=
4.9litre A9L (man) p/n. 92026253 if that helps.


Also cast numbers should read;
day of month= 1 to 31
month of year= A to L (in place of 1 to 12, skip I as not to confuse with number 1)
year= 1 thru to 0 (end of year number)

For example if yours was 15L8 then i would say

15th of december 1978, 1988 or 1998, but VK never produced in any of those years.
other tell tale signs for correct year are CID cast on side, Gear box choice and valley casting etc.

MISTAKE MISTAKE MISTAKE; A9L motor has VC prefix my answer should have read;
Engine prefix VB 4.9litre V5H p/n. 92026253
which is high performance engine which is 304 cid bore 4.00in x stroke 3.02
I believe these motors were fitted to VK HDT group three SS with large valves etc to be homologated to bathurst 84.
Engine was painted black.

CID = the engine size cast on the side of the block.

p/n. 92026253= holdens part number for the V5H engine.

I am not saying that this motor is as holden fitted to SS and chasers but thats what the VB engine number prefix is pointing to. Correct cast date would reveal more.
Original motor would have been fitted with Rochester, Brock type inlet, large valve pollution cyl heads and electronic ignition.

Oh A9L is another code same as L34 bar the rollers etc but i believe this motor to be V5H the hot blue version for brock and the chassers but without the H/D rods like A9L/L34.

Just noticed that the manifold has KC cast on the front (top) of it, you might want to budget for a performer for it, from the feedback ive had KC is one of the worst cast and designed duel plane manifolds avliable, even tracking down a good stocker might be the go.

Just to clear any confusion, this block would have been painted black from the factory, fitted with everything bar rollers, never thought they had the H/D rods tho.
Also thought standard 308/304 code was L31.

did you get the head part nos. yet?
Prolly looking for 92029003
