Clearancing is not that big of a concern. It's the machine work to get everything where it needs to be on a stock block. There is aHP and reliabilty in a stock block and what Mindgame says is true, it's going to cost time and money to get a stock block close and in the end it's going to be less block for the same money.

Just stay NA with that thing and you should be o.k.

I mentioned it in the other thread but the Motown is pretty well clearanced as it is (bores and pan rails). You'll just need a little rub here and there for the 4-inch crank. Cam position is still the same height, so you need to let the cam grinder know what the cam is going in. A little clearancing of the rods will also help.

It's just alot easier with the Motown block. Not to mention the block is alot stronger. Having looked at a few of these since they came out... Mitchell really built this block for the guys who wanna build long stroke strokers (3.875 and up). I'd take it any day over a Bow-tie for this type of build...... and yeah the Iron Eagle and Rocket are even nicer but they will cost you a bit more dinero to put together.

I havent really decided yet what Im gonna do, but I would really like to make a huge displacent SMC. I may be getting a new job with a friend of mines parent company makin alot more cash than I do now so we'll see what happens.

Im going to a huge swap meet in Iola WI, in a few days. Its advertised as like the 3rd largest meet in the US. Maybe Ill come up with something there. I would imigine a meet that big would offer some cool aftermrket stuff. maybe Ill come across a used Dart block or something.

One thing to add, get a Motown or Bowtie block while you're at it because by the time you spend the money to add splayed caps and all the machine work you will only be a few hundred shy of the price of one of these much stronger blocks. Otherwise you will soon be rebuilding especially the guy who wants to add a 200 shot.

You just talked me down from the ledge.I have a 2-bolt 509 production block,4.155 bore,splayed cap,and was going to try a 200 shot this sat. I`ve used a 150 shot a few times and it`s still in one piece.Do you guys think it will survive this level of nitrous for a while?

FWIW,I`ve had this engine apart and found that the machine shop did`nt use torque plates when honing the block.How? There were carbon spots at every head bolt hole about 3/8" wide and 2" long in the cylinders.Thin walls will MOVE!
