My ZZ4 (430) block is 10105123, heads are 62cc 12528826 and cam is 24502586

Clayton, the sad thing is that, if the thing is not a ZZ4, the value is something like a 4X factor, the real ZZ4 being a premium small block and the other being a run of the mill truck engine worth 1/4 of a ZZ4. Unless you paid less than perhaps $750 for the motor, it may have not been a deal.

well i am lucky i guess, I only paid $300 for the enginge, the fellow I bought it from didnt know what it was. I did the research on the numbers and came up with the zz4 factor. my concern now is that it may have been a zz4 that has been rebuilt , i found a reman tag on the side of the engine (glued on) that says remanufactured with a number on it..if this is the case I dont know what cam is in it . but it does not have aluminum heads cast iron heads that look to be late 80s 305..will take it apart..would like to know the condition even if it does look good. thanks
