I have been learning alot from coming here and reading these forums. You guys sure know your stuff! |eek|

I believe the block is an '88 or '89 350 4-bolt main.....On the back of the block is cast 5.7L. On the front it is stamped with VK179027. The crank looks to be forged, going by the wide casting mark. Cast on the crank is 14088532.

Can anyone help me to decifer thse numbers?

thanks! |wavey|

John
