Cracked 502 block
what is the difference between my mercury 502 block casting # 14096859 and a regular 502 block? I am looking at buying a brand new block, but all I can find is automotive blocks. Is there a real difference in block design and material. I have heard that my block is heavier than a normal auto 502. does anyone know where I can find another block like mine? New or used? Thank you in advance.

there is no normal automobile 502 as none came with them.
double check, but it looks like your's is a gen v 502 block. 14096859 Big Block V8 502, 4 bolt, Generation V |

I thought there were some 3500 series trucks that had 502s (8.2 liter) around 2008-2010. No?

yes, rotating assy will work fine in a gen 6 block
|
Will my heads and intake work off my Gen V block? I would like to use my same heads. Thanks in in advance again |
Yes........^^^^ the gen VI uses a step nose cam design and a retainer ring that keeps it from walking around, dont think the gen V is like that.

A mark iv crank will work in a gen 6 block but you will have to convert to a two piece rear seal, mark 4 cam will not fit/work in a Gen 6 pistons and rods are all interchangeable as well as the heads. Flat lifters will work but don,t make much sense to use them when it's made for rollers. Oil pans are not interchangeable along with the timing chain and sprockets. |

there is no such thing as a mark v block,their is mark iv,gen 5 and gen 6.both gen 5 and gen 6 use a one piece rear main seal.gen 6 is the only one that comes with a step nose cam but all big blocks can be used with a step nose cam.the cam from the gen 5 can be used in a gen 6 block.the gen 5 heads will work on the gen 6 block.

Thanks to every one, I am now looking at dart and world product blocks. for more strength for about the same price. I will let you know what I come up with,
|
imo the dart block is the best.

Also don't overlook the Brodix iron blocks.

agree, and make sure you check the lifter bores...........:D

You will need to check and double check every machined surface no matter what block you choose. You need a good machine shop and some accurate measuring tools to end up with anything worth your time. I also prefer the Dart big M |
