69 N.O.X. RATT

You have the 300 HP 350. I think you have a misprint on the heads it should be 3927186, that would make them 300 hp 350 heads as well. Both are original 69 parts. :chevy

Looks like a 69 Vette engine.

19s721299 brakes down as 1=Chevy, 9=year, S=St Louis, 721299=last six of VIN.

vo3235hx?? Sure it is not V0323HX?? One number too many in there. If so it is V=Flint engine plant, 0323=engine build date (Mar23), HX=69 Vette 350ci/350hp with manual trans and A/C.

The following is according to MSA Small Block Number Guide........
Other members may have different info.

19s727299....should match your VIN# to be numbers match.

vo3235hx......
v=flint engine plant
hx= 1969 350hp 350 (L-46) with 4 speed
double check the 03235 # this should be an assembly date. Too many numbers.

3956618 = block casting # used 68-79 for 302 / 327 / & 350 blocks.

G189= date code July 18th 1969

head casting 3927186 common # for 68-72, this application should be
1.94 / 1.5 valves 63.3 cc.

0209= date code Feb 1969.


Hope this helps,
