Only problem with that, is that it has the goofy head bolt pattern and I don't want to be commit to running their head if I do the 6 bolts/cyl.
Honestly, I would love to go with the RHS block but with the limited bore size I can't get the CI I want to run.
ERL block is starting to look like a more viable option at this point. The sleeves can be made a little longer.
Honestly, I would love to just go lsx but I don't want the weight of the iron block. The damn C5R block is an expensive piece, dart billet is even worse at this point it's out of consideration, just too much $ for what I want to do/have to spend.

What is the max bore for the RHS block?
How much $ is the RHS block?
Then what is the max bore for the Dart Billet block?
How much $ is the Dart block?
The RHS block is around the 4K mark, and the max bore is 4.16 on that one, but you can get that in a tall deck.
The dart billet block last time I looked into it was over 7 grand, but I think you can go 4.18 on that, if I remember right. That block also is available in any deck height, raised cam, shifted oil galley for stroke clearance, hell if you want no coolant passages at all you can do that too.
The dart billet piece, definately hs a killer item, but you're probably looking at 10 grand for the block and the machine work by the time you're done. Way out of my budget range at this point.

I agree, what is the point of a tall deck without a raised cam? I suppose we can go smaller and smaller on the rod journals? I would hate to have a long stroke just to end up with a compromise using a small base circle cam and connecting rods that need to be clearanced.

It is still $2,250 cheaper than a C5R block and probably stonger, plus it already has the GM 6 bolt head pattern.
Or am I missing something?
Problem is the limitation on the bore, you can only go 4.16 with it. But, a tall deck on that block and I would think a square 4.125/4.1 motor should be possible, givign ya a 434
Should work, at least I'd think.
I just don't know about the headers and whatnot, will the regular ones fit, if not who's making some that do, and what are they gonna cost, what about everything else on the motor too..... that type of thing.
