I am sure they would cost you more then a set of dart or merlin blocks anyway. Using the adapters to put a two piece rear main crank in a one piece rear main block is a good alternative. The oiling setup on the gen6 blocks is improved over the mk4 blocks from what I understand. The aftermarket blocks also take advantage or the oiling upgrades too.
You are correct that the newer blocks have better oiling. Eddie |

You pretty much nailed it. The seal adapters to put a Mk IV crank in a Gen V/VI block is only about $80. They work well.

Yes. Get em. They aren't that easy to find used. They are available new for somewhere around $1500. I may be able to find a few a little cheaper. Had a line on a few a while back, but I really didn't need them. Let me see what I can come up with. I'll let you know.

The biggest issue with the mark 502 was cooling issues.the newer gen v was revised for better cooling then they did another revision on the gen6 to make it better and also decided to add the roller cam set up..

What's the going rate for 502 blk needing to be machined, etc.? And for its worth again, my last build was 454 to 489 and picked up 6-7 mph in my 23.5 Arriva |
