I have a supposed ZZ4 block with a block casting number of 10243880. Of all the research I've done, it should be a 4 bolt block but I have only 2 bolt mains. It does have a roller rocker cam and lifters though.
Does anyone know what this engine came from or what exactly it is? I cant find anywhere that its stamped with ZZ4.
It has a stamp on the front boss of VF036151
Any info would be helpful,
Thank you,
Vern

hmmm...funny thing, mine's a 10243880 2-bolt as well...mexico eh? good block? I had it gone through and upgraded all the rings and bearings before it was reassembled...wasn't crazy about the cast iron heads so went with Edelbrock vortec heads #60975
They are fine, imo better castings than the old stuff. Bought one yrs ago from P.A.W. it needed very little machine work.
TheZZ4 never came with iron heads?

Mine did, 14096210 64cc. The cam I put in would drive quite a bit of machine work, so I went with the head that came already hooked up. well worth the money.
I also have a 010 4 bolt main and the casting numbers are 16J335283
10530cmj
ive seen alott of different information im not even sure exactly whate year block i have nor what it came out of
Can anyone help decode the casting number THANKS
